Question

A charge of `30 C` passes through a circuit every `5 s`. If the circuit can generate `12 W` of power, what is the circuit's resistance?

Answer 1

`R=1/3 ohm`

Explanation:

`"The electric current is determined by:"`
`I=(Delta Q)/(Delta t)`
`"I:electric current"`
`"Q:charge"`
`"t:time"`
`I=30/5`
`I=6A`
`"P:Power ;R: resistance of circuit"`
`P=I^2R`
`12=36*R`
`R=1/3 ohm`
