$P = 6 W$

There are 3 variations of the power formula:

$P = V*I, " "P = I^2*R, " and " P = V^2/R$

If you know any one of them, the others are available thru the use of Ohm"s Law and a bit of algebra.

For this problem, use $P = V^2/R$

$P = (12 V)^2/(24 Omega) = 6 V^2/Omega = 6 W$

I hope this helps,

$6$ watts

Power in this case is given by the equation:

$P=V^2/R$

where:

$P$ is the power in watts

$V$ is the voltage in volts

$R$ is the resistance in ohms

So, we get:

$P=(12 \ "V")^2/(24 \ Omega)$

$=(144 \ "V"^2)/(24 \ Omega)$

$=6 \ "W"$
