The rms value of current I ( rm...

The rms value of current ` I _ ( rms )` is

A

` ( I _ 0 ) /( 2pi ) `

B

` ( I _ 0 ) /( sqrt 2 ) `

C

` ( 2 I _ 0 ) /( pi ) `

D

` sqrt 2 I _ 0 `

Text Solution

Verified by Experts

The correct Answer is:
B
The ` I _ (rms ) ` value of current ,
`I _ (rms ) = ( I _ 0 ) /( sqrt 2 ) `
( where, `I _ 0 ` is the peak value of current )
