A coil (inductor) is a wire wound into a number of loops. If you suddenly change the voltage applied across a coil (inductor), why doesn't the current change almost instantaneously to be equal to the voltage across the coil divided by the resistance of the coil as happens with an (Ohmic) resistor or piece of straight wire?
Homework Answers
With a decreasing current, the voltage polarity will be oriented so as to try to keep the current at its former magnitude. In this scenario, the inductor will be acting as a source, with the negative side of the induced voltage on the end where electrons are exiting, and the positive side of the induced voltage on the end where electrons are entering. The more rapidly current is decreased, the more voltage will be produced by the inductor, in its release of stored energy to try to keep current constant.
