Front

What is the unit of electrical resistance?

Back

Ohm (Ω)

Front

What is the relationship between voltage (V), current (I), and resistance (R) in a circuit?

Back

V = I × R (Ohm's Law)

Front

What type of circuit has multiple paths for electricity to flow?

Back

A parallel circuit.

Front

What happens to the total resistance in a series circuit when more resistors are added?

Back

The total resistance increases.

Front

What happens to the total current in a parallel circuit when more branches are added?

Back

The total current increases.

Front

If a circuit has a voltage of 12 volts and a resistance of 4 ohms, what is the current?

Back

3 amps (I = V/R)
