Question

How much power is produced if a voltage of `7 V` is applied to a circuit with a resistance of `400 Omega`?

Answer 1

Power`=0.1225` Watt

Explanation:

Data:-
Power`=P=??`
Voltage`=V=7V`
Resistance`=R=400Omega`
Sol:-
We know that:-
`P=V^2/R`
`implies P=7^2/400=49/400=0.1225` Watt

`implies P=0.1225` Watt
