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

We have been given that

Time period of emf is

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

As we know,

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

We have been given that

Peak voltage

Peak current

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

As we know ,

Inductive Reactance ;

Also we know that , is angular frequency of current

Thus, this is the value of inductance.
