What is Faraday's Law?
What is Faraday's Law?
- The law that states that the induced voltage in a circuit is directly proportional to the rate of change of magnetic field through the circuit (correct)
- The law that states that the induced current in a circuit is inversely proportional to the rate of change of magnetic field through the circuit
