The heat Produced in a given resistor in a given time by the sinusoidal current

I_0 \sin

\omega \mathrm{t}

will be the same as that by a steady current of magnitude

View answer and explanation

Correct option: D

\frac{I_0}{\sqrt{2}}

Option D (

\frac{I_0}{\sqrt{2}}

) is correct because the RMS value of a sinusoidal current is

I_0/\sqrt{2}

, and the heat produced is proportional to the square of the RMS current.
