Question

A charge of `12 C` passes through a circuit every `6 s`. If the circuit can generate `8 W` of power, what is the circuit's resistance?

Answer 1

The resistance is 2 ohm

Explanation:

I= `q/t` here I = current strength,q = charge passing in t sec = 12C
and t =6 sec. So i = 2amp
power (P) = `I^2R`, where R = Resistance
P= 8W Hence R= `8/(2*2)` =2ohm
