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

Sagot :

The power output of the cells is 6 watts and the resistance inside the phone is 6 Ohms.

What is power output?

Power Output can be defined as the average rate of electric energy delivery in a circuit.

The S.I unit of power is Watts (W)

Resistance can be defined as the opposition to the flow of electric current caused by a substance.

The S.I unit of resistance is Ohm, denoted with the symbol (Ω)

How to calculate the power output and resistance

Using the formula given;

Power output, P = VI

where V = voltage = 0.5 × 12 V = 6V

I = current = 1 A

Power output = 6 × 1 = 6 Watts

Resistance = V ÷ I = 6 ÷ 1 = 6 Ohms

Therefore, the power output of the cells is 6 watts and the resistance inside the phone is 6 Ohms.
