Question

How much power is produced if a voltage of `8 V` is applied to a circuit with a resistance of `64 Omega`?

Answer 1

`1 W`

Explanation:

Current equals Voltage divided by Resistance
`I=V/R = (8 V)/(64 Omega) = 1/8 A`
`color(white)("XXXXXXXXXXXXX")1 A"mp" = (1 V"olt")/(1 "Ohm")`

Power equals Voltage times Current
`P = V*I = 8 V xx 1/8 A = 1 W`
`color(white)("XXXXXXXXXXXXX")1 W"att" = 1 V"olt"*A"mp"`
