The heat produced in a given resistor in a given time by the sinusoidal current `I_(0)` sin `omegat` will be the same as that by a steady current of magnitude .

A

`0.707 I_(0)`

B

`1.412 I_(0)`

C

`I_(0)`

D

`sqrt""I_(0)`

Verified by Experts

The correct Answer is:

A

Heat produced by AC is
Heat produced by Dc is `I^(2)R`
`I_("RMS")^(2) = I^(2)R`
`therefore I = I_("rms") = I_(0)//sqrt""2 = 0.707 I_(0)`
