Front

What is resistance?

Back

How much a given device resists the flow of electric current.

Front

Which is the right form of Ohm's Law?

Back

I = V / R

Front

What unit is used to measure current?

Back

Amps

Front

What unit is used to measure voltage?

Back

Front

What does Ohm's Law state?

Back

The current through a conductor between two points is directly proportional to the voltage across the two points.

Front

What is the formula to calculate resistance?

Back

R = V / I

Back

Watts (W)

Front

What is the relationship between power, voltage, and current?

Back

P = V * I

Front

What is a circuit?

Back

A closed loop that allows current to flow.
