To calculate the power rating, we use the formula P = V x I, where P is power in watts, V is voltage in volts, and I is current in amperes.
Given:
V = 9V
I = 45mA = 0.045A
P = 9V x 0.045A
P = 0.405 watts
Therefore, the power rating of the DC battery is 0.405 watts.
Given:
V = 9V
I = 45mA = 0.045A
P = 9V x 0.045A
P = 0.405 watts
Therefore, the power rating of the DC battery is 0.405 watts.
