Question

A charge of `24 C` passes through a circuit every `16 s`. If the circuit can generate `32 W` of power, what is the circuit's resistance?

Answer 1

`R=21.33ohm`

Explanation:

Charge=24C
And time =16s

`I=C/t`
`I=1.5A`

Now using direct formula for power

`P=I^2R`
`R=P/I^2`
`R=32/1.5`
`R=21.3333333333ohm`
