Short Answer

A inductor is connected across an AC generator that produces a peak voltage of . What is the peak current through the inductor if the emf frequency is (a) ? (b) ?

(a) Peak current is

(b) Peak current is

See the step by step solution

Step by Step Solution

Part(a)Step 1: Given information

We have been given that,

Inductance of inductor is,

Peak Voltage is, and frequency

Part (a) Step 2: Simplify

Let inductive reactance is,

We know that in inductive circuit reactance is given as,

By ohm's law, we know that,

Hence, Current is

Part (b) Step 1: Given information

We have been given that,

Frequency is,

Part (b) Step 2: Simplify

Let inductive reactance is,

We know that in inductive circuit reactance is given as,

By ohm's law, we know that,

Hence, Current is
