A. 50 ohms (120/2.4)

An inductor is connected to a 120V 60Hz Supply. The current is 2.4A. What is the inductive reactance

A. Inductance

Current flowing though a conductor, and particularly through a coil causes a magnetic field around the conductor or coil. The magnetic field intern induces voltage back into the original conductor or coil which is opposite in polarity to the Applied voltage. This action is caused by a characteristic named...

Ratio of resistance as compared to Inductance

In a pure inductive circuit, current lags voltage by

What is the symbol for inductive reactance

C. Induced Voltage

When AC current flows through an inductor a magnetic field is created which is continually increasing decreasing and reversing polarity. Because of this a voltage is created in the conductor which is called
