#### Explanation:

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

I hope this helps,

#### Explanation:

Power in this case is given by the equation:

where:

#P# is the power in watts

#V# is the voltage in volts

#R# is the resistance in ohms

So, we get:
