Front

What is the unit of Electric Current?

Back

Electric Current is measured in Amperes (A).

Front

What is the relationship between Voltage, Current, and Resistance?

Back

Ohm's Law states that Voltage (V) = Current (I) × Resistance (R).

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

Back

The total resistance increases when more resistors are added in series.

Front

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

Back
