Inductors: Current & B Field Circuits, Second Edition by Fawwaz T. Ulaby and Michel M. Maharbiz, © NTS Press, Used with Permission by the Publisher Current = begins to flow and starts to create magnetic field

Inductors: Current & B Field Circuits, Second Edition by Fawwaz T. Ulaby and Michel M. Maharbiz, © NTS Press, Used with Permission by the Publisher Current = begins to flow in and starts to create magnetic field At t=0, this acts like an OPEN circuit Voltage is high, current is low

Inductors: Current & B Field Circuits, Second Edition by Fawwaz T. Ulaby and Michel M. Maharbiz, © NTS Press, Used with Permission by the Publisher When magnetic field is established, current flows freely At t=∞, this acts like a SHORTcircuit Voltage is low, current is high

What does an inductor do to the current ? 14

What does an inductor do to the current ? 15 Vs/R 66% at t=L/R 

What does an inductor do to the voltage ? 16 Vs 36% at t=L/R 

What does an inductor do to a voltage and current? t=0: OPEN CIRCUIT t=∞: SHORT CIRCUIT 17 Voltage changes Instantly Current changes slowly At ‘steady state’ Voltage =0 At ‘steady state’ Current is Vs/R
