Answer

Explanation:

Step1: Recall power - formula

The formula for power is $P = VI$, where $P$ is power, $V$ is voltage, and $I$ is current.

Step2: Substitute given values

Given $V = 12$ volts and $I=6.5\times 10^{- 2}$ amps. Substitute into the formula: $P=(12)\times(6.5\times 10^{-2})$.

Step3: Calculate the product

$(12)\times(6.5\times 10^{-2})=(12\times6.5)\times10^{-2}=78\times10^{-2}=0.78$ watts.

Answer:

A. 0.78 watts
