Question

If 12 photovoltaic cells at 0.5 V each produce a total of 6 V of potential energy and carry a 1A current to your phone, what is the power output of these cells and the resistance inside your phone? P = VI and R = V/I (Show calculations and units)

Answer 1

The power output is 6 W. The resistance is 6 Ω.

Explanation:

Power output= 6V * 1 A= 6W

Resistance= 6V/1A= 6 Ω
