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

Short Answer

Expert verified

a. frequency, f is $50 H z$

b. $L = 1.5915 \times 10^{- 3}$ H

Step by step solution

part a) step 1: Given information

We need to find the Emf frequency f using the given graph

part a) step 2 : Detailed solution

As we know,

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

f = \frac{1}{T} = \frac{1}{0.02} \Rightarrow f = 50 H z

part b) step 1 : Given information

We have to find out the inductance, L using the graph and given values

Detailed solution

As we know that inductive reactance;

$X_{L} = \frac{V_{m a x}}{I_{m a x}} = \frac{1 V}{2 A} = 0.5 Ω \Rightarrow X_{L} = ω L$ where $ω$ is angular frequency of current

$ω = 2 π f = 2 π \times 50 = 100 π \Rightarrow L = \frac{X_{L}}{ω} = \frac{0.5}{100 π} \Rightarrow L = 1.5915 \times 10^{- 3} H$
