A current l=3+8 sin 100t is passing through a resistor of resistance 10 `Omega`.The effective value of current is

A

`5 A`

B

`10 A`

C

`4sqrt2 A`

D

3sqrt2 A

Text Solution

Verified by Experts

`(a) l_(effective)^(2)=l_(rms) (overset(T)underset(0)int l^(2) dt)/(overset(T)underset(0)int dt)`
After solving,` l_(effective)^(2)=l_(rms)=5A`
