Question 1 of 5

What is the relationship between voltage (V), current (I), and resistance (R) according to Ohm's Law?

Ohm's Law states that voltage is directly proportional to current and resistance.
Question 2 of 5

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

Using I = V/R, the current is 12V / 4 ohms = 3A.
Question 3 of 5

Resistance is measured in:

Resistance is always measured in Ohms.
Question 4 of 5

If the current in a circuit is 2A and the voltage is 6V, what is the resistance?

Using R = V/I, the resistance is 6V / 2A = 3 ohms.
Question 5 of 5

What happens to the current in a circuit if the voltage is doubled and the resistance remains the same?

According to Ohm's Law (I=V/R), current is directly proportional to voltage.
