• 1. pressure of electrical circuit

• 1. potential difference

• 1. all are correct

______ is used to measure the voltage of two points in any circuit.

• 1. Voltmeter

• 1. Multimeter

• 1. Ammeter

• 1. a & b are correct

AC voltages are produced by Generator. 

• True

• False

DC voltages are produced by _________

• 1. generator

• 1. battery

When the voltages are high, then the flow of electrical current is ________

• 1. high

• low

The symbol of voltage is V or E.

• True

• False

The negative and positive charge symbols are assigned (in that order) to the

• proton and electron

• atom and nucleus

• electron and proton

• electron and element

A voltmeter is used

• to measure current

• in series with the circuit

• in parallel with the circuit

• to measure coulombs

If the current in a circuit equals 0 A, it is likely that the

• voltage is too high

• resistance is too low

• circuit has a short

• circuit is open

What are the unit and symbol for current?

• Ampere, A

• Coulomb, I

• Ampere, Q

• Ampere, I
