Question 1

Define Ohm’s Law in the relationship of voltage to current and resistance.

Answer 1

Voltage (V) = Current (I) × Resistance (R).

Question 2

Define Ohm’s Law for the relationship of current to voltage and resistance.

Answer 2

Current (I) = Voltage (V) / Resistance (R).

Question 3

Define Ohm’s Law for the relationship of resistance to voltage and current.

Answer 3

Resistance (R) = Voltage (V) / Current (I).

Question 4

Using Ohm’s Law, solve for voltage when given current as 2 amps to the resistance of 5 Ohms.

Answer 4

Voltage (V) = Current (I) × Resistance (R) = 2A × 5Ω = 10V.

Question 5

Solve for unknown current when given the voltage is 12 volts and the resistance is 6 Ohms.

Answer 5

Current (I) = Voltage (V) / Resistance (R) = 12V / 6Ω = 2A.

Question 6

Solve for resistance when given the voltage of 120VDC and the current is 60A.

Answer 6

Resistance (R) = Voltage (V) / Current (I) = 120V / 60A = 2Ω.
