What is static electricity?
An imbalance of electric charges on a material's surface
A magnetic effect produced by moving charges
A flow of electrons through a conductor
Alternating current in a circuit
Static electricity arises when there is an imbalance of electric charges on the surface of a material. These charges remain until they are able to move away via a conductor or air gap. This phenomenon is different from current electricity, which involves a steady flow of charges through a conductor. For more details, see Wikipedia.
Which process primarily generates static electricity when two materials contact and then separate?
Friction
Conduction
Radiation
Induction
Friction generates static electricity by causing electrons to transfer from one material to another when they are rubbed together. This transfer results in one object becoming negatively charged and the other positively charged. The effect is most pronounced in dry conditions where moisture does not dissipate the charges. Learn more at Khan Academy.
Which of the following materials is a good electrical insulator?
Copper
Gold
Rubber
Aluminum
Rubber is a good insulator because it has very high electrical resistivity, preventing electrons from moving freely. Conductors like copper, aluminum, and gold allow electrons to move easily. Insulators are used to prevent unwanted flow of current and protect against shocks. See more at Britannica.
What common phenomenon occurs when you touch a metal doorknob after walking on a carpet?
Electrolysis
Static shock
Magnetization
Conduction heating
The little spark you feel is a static shock caused by sudden discharge of built-up static electricity. Your body accumulates charge from the carpet, and touching a conductor like a doorknob allows charges to equalize. The tiny spark is the visible and tactile effect of this discharge. More info at Explain That Stuff.
Which type of charges repel each other in static electricity?
Induced charges
Neutral charges
Same charges
Opposite charges
According to Coulomb's principle, like charges (both positive or both negative) repel each other, while opposite charges attract. This fundamental behavior explains many static electricity phenomena. Neutral objects neither attract nor repel unless they become charged. For more, see Coulomb's Law.
When a charged object is brought near a neutral conductor without touching, what phenomenon causes charge separation within the conductor?
Conduction
Discharge
Induction
Polarization
Electrostatic induction occurs when a charged object near a conductor causes electrons within the conductor to move, creating regions of positive and negative charge. No direct contact is needed for this separation. The effect is widely used in devices like capacitors and electrostatic shields. Read more at Wikipedia.
Which law quantifies the force between two point charges?
Ohm's Law
Coulomb's Law
Gauss's Law
Faraday's Law
Coulomb's Law defines the electrostatic force between two point charges as proportional to the product of their charges and inversely proportional to the square of their separation. It forms the basis for classical electrostatics calculations. The constant of proportionality is the Coulomb constant. Details at Wikipedia.
What is the SI unit of electric charge?
Volt
Ohm
Coulomb
Ampere
The coulomb (C) is the SI unit of electric charge, defined as the amount of charge transferred by a current of one ampere in one second. It is one of the seven base units in the International System of Units. For more, visit Wikipedia.
How does humidity affect the buildup of static electricity?
Increases buildup due to moisture acting as a conductor
Decreases buildup because moisture helps dissipate charges
Reverses the charge polarity
Has no effect on static electricity
High humidity reduces static electricity because water molecules in the air help neutralize and dissipate charges on surfaces. In dry conditions, charges remain and accumulate, leading to more static shocks. This is why winter months often produce more static buildup. More details at Science Learning.
In dry conditions, which fabric is more likely to generate static electricity when rubbed?
Wool
Silk
Cotton
Polyester
Polyester is a synthetic fabric that tends to gain or lose electrons easily when rubbed, leading to static buildup. Natural fibers like cotton and wool are less prone to static generation in dry conditions. That's why synthetic clothing often leads to more static cling. See Laundry Care.
Which concept describes a material's tendency to gain or lose electrons in static interactions?
Dielectric constant
Resistivity
Triboelectric series
Conductivity
The triboelectric series ranks materials by their tendency to gain or lose electrons when in contact and then separated. Materials higher in the series tend to lose electrons and become positively charged, while those lower gain electrons. This ordering helps predict static charge generation. Further reading at Wikipedia.
What device uses a moving belt to accumulate static charge on a hollow metal globe?
Tesla coil
Van de Graaff generator
Wimshurst machine
Cyclotron
A Van de Graaff generator uses a moving belt to transport charge to a hollow metal globe, creating very high voltages. The charge accumulates until it discharges, often producing visible sparks. This device demonstrates principles of electrostatics and high-voltage phenomena. See Wikipedia.
What phenomenon occurs when air around a sharp conductor ionizes due to high voltage, producing a faint glow?
Corona discharge
Dielectric breakdown
Superconductivity
Photoelectric effect
Corona discharge occurs when the electric field near a sharp conductor is strong enough to ionize nearby air molecules, creating a glow and hissing sound. It often happens at high voltages in power lines and lightning rods. The effect leads to energy loss and ozone production. More at Wikipedia.
What is the approximate breakdown voltage in air at sea level per centimeter of gap?
30 kV/cm
300 kV/cm
1 kV/cm
3 kV/cm
Air at sea level typically breaks down at around 30 kilovolts per centimeter, leading to electric sparks or lightning. Below this threshold, air remains an insulator; above it, rapid ionization occurs. This value varies slightly with humidity and pressure. Reference: HyperPhysics.
Which law describes that the net electric flux through a closed surface is proportional to the enclosed charge?
Coulomb's Law
Ampère's Law
Gauss's Law
Kirchhoff's Voltage Law
Gauss's Law states that the net electric flux through any closed surface equals the enclosed charge divided by the permittivity of free space. This principle simplifies many electrostatic calculations, especially with symmetrical charge distributions. It is one of Maxwell's equations. Details at Wikipedia.
Which factor does NOT affect the amount of static charge generated through friction?
Contact force
Surface area in contact
Distance from ground
Material type
Charge generation by friction depends on the materials involved, the contact force, and the contact area. Distance from ground does not influence the amount of charge produced during rubbing - it only affects how the charge may later dissipate. Grounding impacts discharge, not generation. Learn more at The Physics Classroom.
In electrostatics, the electric potential inside a hollow conducting shell is:
Constant and equal to the potential at the surface
Undefined (infinite)
Zero relative to infinity
Varying with distance from the center
Inside a hollow conductor in electrostatic equilibrium, the electric field is zero, which means the electric potential is constant throughout the interior. That constant value equals the potential at the conductor's surface. This is a direct result of Gauss's Law and electrostatic shielding. More at Wikipedia.
