Question

A charge of `6 C` passes through a circuit every `3 s`. If the circuit can generate `6 W` of power, what is the circuit's resistance?

Answer 1

1,5 Ohm

Explanation:

the current is given by the charge that flow in 1 second than 6C/3s = 2 Ampère. the electric power is given by `P = Ri^2` then `R =P/i^2 = (6W)(/2A)^2= 1,5 Ohm`
