NEET UG PHYSICS MCQ: ALTERNATING CURRENT

1 Medium

1 of 1

Application +4 | -1

The instantaneous current and voltage of an AC circuit are given by

i=10 \sin (314 t) A

and

V=100 \sin (314 t) V

What is the power dissipation in the circuit?

View answer and explanation

Correct option: B

500 \mathrm{~W}

Option B (500 W) is correct because the power dissipation is calculated as P = Vrms * Irms, where Vrms and Irms are the root mean square values of voltage and current.
