Electricity and Ohm's Law

A light circuit is operating at 75 Volts. What is the circuit's current if the resistance is 5 Ohms?

• 375 Amps

• 50 Amps

• 15 Amps

• 0.07 Amps

What is the voltage if a resistance of 25 Ω produces a current of 250 amperes

• 6250V

• 10V

• 0.1 V

• 625 V

What is the current produced by a voltage of 240 V through a resistance of 0.2 Ω
