Ohm's Law says V = IR and P = VI

Apply your values and solve the power equation.

Solve for I from the first equation and your values. Then use that value in the second equation to find the power.

V = IR and P = VI where P = Power in Watts, I = current in Amperes, and V = voltage in Volts, and R = resistance in Ohms.
