Question

Electric Charge can be Positive (like in the Atomic Nucleus) or Negative (like in the Electrons).

True

False

A plastic rod can be electrically charged by rubbing with a piece of clothe.

True

False

Electric Charge is typically measured in units of C ("Coulomb"). 1 C involves some 6.25 billion billion electrons.

True

False

The Electric Field may be geometrically described by the "lines of force".

True

False

Metals are typical conductors where a gas of free electrons may move around.

True

False

The forces exerted between Electric Charges can be calculated by a Law that was experimentally discovered by:

B. Franklin

Coulomb

Newton

None of the above

None of the above

The Electric Potential, measured in Volts, is related tho the Electric Potential Energy by the formula O Electric Potential = Electric Charge x Electric Potential Energy Electric Potential -Electric Charge Electric Potential Energy Electric Potential Electric Potential Energy Electric Charge None of the above

Explanation / Answer

TRUE TRUE 6.2415 × 10^18 no of electrons in 1C charge charge on 1 e=1.6*10^-19 So in 1C 1/1.6*10^-19 TRUE V=U/q   C option TRUE NO, a flow or current of free electrons through a solid body. If flow is not hindered then Conductor Coulomb Known as Coulomb ‘s Law
