In a LCR oscillatory circuit find the energy stored in inductor at resonance. If voltage of source is 10 V and resistance is `10Omega and inductance = 1H.

A

0.5 J

B

2 J

C

4 J

D

10 J

Text Solution

Verified by Experts

The correct Answer is:
A
At resonance current
`l=(V)/(z_("min"))=(V)/(R)=(10)/(10)=1A`
Energy of inductor `=(1)/(2)Ll^(2)=(1)/(2)(1)(1)^(2)=0.5J`
