Test: Energy Stored in an Inductor - Question 1
Save

If the current in a coil having a constant inductance of L henrys grows at a uniform rate, what is the value of the average current?

Detailed Solution for Test: Energy Stored in an Inductor - Question 1

The average current is the average of the current which flows in the inductor. Hence it is I/2.

Test: Energy Stored in an Inductor - Question 2
Save

What is the power in the magnetic field if the current in a coil has a constant inductance of L henrys grows at a uniform rate?

Detailed Solution for Test: Energy Stored in an Inductor - Question 2

The average current is I/2. The e.m.f. induced in the coil is LI/t V. Power= VI, hence the average power= I/2*LI/t.

 What is the energy stored in the magnetic field if the current in a coil has a constant inductance of L henrys grows at a uniform rate?

Detailed Solution for Test: Energy Stored in an Inductor - Question 3

The average current is I/2. The e.m.f. induced in the coil is LI/t V. Power= VI, hence the average power= I/2*LI/t. The total energy stored= power*t= LI2/2.

emf= LI/2t
Substituting the values from the given question, we get emf= 2.5V.

Test: Energy Stored in an Inductor - Question 8
Save

 Calculate the value of emf in an inductor if the value of inductance is 15H and an average current of 5A flows through it in 10s.
Detailed Solution for Test: Energy Stored in an Inductor - Question 8

The expression for emf in an inductive circuit is:
emf= LI/2t, where I/2 is the average current.
Substituting the values from the given question, we get emf= 2.5V.

Test: Energy Stored in an Inductor - Question 9
Save

Calculate the current in an inductor if the energy stored is 160J and the inductance is 20H.
Detailed Solution for Test: Energy Stored in an Inductor - Question 9

The expression for energy in an inductor is:
W= LI2/2t
Substituting the values from the given question, we get I=4A.

Test: Energy Stored in an Inductor - Question 10
Save

Find the time taken for the current in an inductor to change to 2A from 0A if the power in the inductor is 5W. The value of inductance is 10H.
Detailed Solution for Test: Energy Stored in an Inductor - Question 10

The expression for power in an inductive circuit is:
P= LI2/2
Substituting the values from the given question, we get t=4s.
