As per the question we are asked to calculate the average power produced by flashlight.

It is given that the voltage [V] = 12 volts.

The current flowing through the circuit [I]
$= 6.5*10^-2\ ampere$

The power consumed in an electrical circuit is the product of voltage and current flowing through that circuit. Mathematically it can be written as -

power = voltage×current

i.e P = VI [here p is the power]

Putting the values of V and I the power is calculated to be-

P = VI

$= 12 volt*6.5*10^-2\ ampere$

=0.78 watt

Here watt is the unit of electric power.
