# FIGURE EX32.24 shows voltage and current graphs for an inductor.a. What is the emf frequency ?b. What is the value of the inductance ?

a. The emf frequency

b. The inductance

See the step by step solution

## Part a) Step 1 : Given information

We have been given that

Time period of emf is

We have to find emf frequency by using the voltage and current graph .

## Step 2 : Detailed solution

As we know,

Emf frequency is the number of oscillations in voltage in one second

## Part b) Step 1 : Given information

We have been given that

Peak voltage

Peak current

We need to find out the inductance of the inductor using graph and given values .

## Step 2 : Detailed Solution

As we know ,

Inductive Reactance ;

Also we know that , is angular frequency of current

Thus, this is the value of inductance.
