Question

A charge of `16 C` passes through a circuit every `8 s`. If the circuit can generate `36 W` of power, what is the circuit's resistance?

Answer 1

`R=9 ohm`

Explanation:

`"The electric current is determined as charge passed through a circle in per second"`
`I=(Delta Q)/ (Delta t)`
`I=16/2=2A`
`P=I^2*R`
`36=2^2*r`
`36=4*R`
`R=36/4`
`R=9 ohm`
