electromagnetic induction

what does -L dL/dt represent?

The back EMF produced by the inductor. This term is associated with Faraday’s Law and Lenz’s Law.

What does Faraday’s law state?

Faraday’s law states that the magnitude of the induced EMF in a circuit is directly proportional to the rate of change of flux linkage.

What does Lenz’s Law state?

Lenz’s law states that the direction of the induced EMF is such that it opposes the change causing it.

Define self-inductance

Self-inductance is defined as the measure of the ability of a coil to give rise to the back EMF.

What is the root mean square value of an alternating current Irms?

The Irms is numerically equal to that steady current that dissipates heat at the same rate in a given resistor.

What is the root mean square value of an alternating Voltage Vrms?

Vrms is numerically equal to that steady voltage that dissipates heat at the same rate in a given resistor.
