If the current is halved in a coil, then the energy stored is how much times the previous value

A

`E_(2)=E_(1)`

B

`E_(2)=2E_(1)`

C

`E_(2)=1/2E_(1)`

D

`E_(2)=1/4E_(1)`

Text Solution

Verified by Experts

The correct Answer is:
D

`E_(2) = 1/2 L[1/2]^(2) = 1/4 [1/2 LI^(2)]=(E_1)/4`.

How is energy stored in a clock ?

Magnetic field energy stored in a coil is

Two different coils have self inductances L_1=9mH and L_2=2mH . The current in one coil is increased at a constant rate. The current in the second coil is also increased at the same constant rate. At a certain instant of time, the power given to the two coils is the same. At that time, the current the induced voltage and the energy stored in the first coil are i_1,V_1 and W_1 respectively. Corresponding values for the second coil at the same instant are i_2,V-2 and W_2 respectively. Then,

On passing a current of 2A in a coil inductance 5H, the energy stored in it will be-

Two different coils have self-inductances L_(1) = 8 mH and L_(2) = 2 mH . The current in one coil is increased at a constant rate. The current in the second coil is also increased at the same constant rate. At a certain instant of time, the power given to the two coil is the same. At that time, the current, the induced voltage and the energy stored in the first coil are i_(1), V_(1) and W_(1) respectively. Corresponding values for the second coil at the same instant are i_(2), V_(2) and W_(2) respectively. Then:
