Front

What is voltage?

Back

The potential for electricity flow.

Front

What is current?

Back

The amount of electricity flowing through a circuit.

Front

What is resistance?

Back

The obstruction to electricity flow.

Front

What is voltage drop?

Back

The amount of voltage used up by a particular component.

Front

When checking resistance in a circuit, what is the most important thing to remember?

Back

That the circuit is isolated from the power, ground, and control modules.

Front

What is the voltage of a series circuit if current is measured at 3.0 amps and resistance at 24 ohms?

Back

72 volts.

Front

What is the most accurate way to find small resistances to current flow in a circuit?

Back

Perform a voltage drop test.

Front

What is the most important aspect of a wiring repair?

Back

A strong mechanical and water-tight connection.

Front

When making a voltage drop test, what are the two most important things to remember?

Back

The circuit must be under load and the meter must be placed across the suspected resistance.

Front

What happens when one of the wires on one of the branches in a parallel circuit of lightbulbs breaks?

Back

The other light remains illuminated.
