What potential (voltage) exists between two power supply terminals if 5 joules of energy are required to move 10 coulombs of charge between the two terminals?

The potential difference (voltage) between two points can be calculated using the formula:

V = E / Q

Where: V is the potential difference in volts (V) E is the energy in joules (J) Q is the charge in coulombs (C)

Here are the steps to calculate the potential difference:

1. Identify the energy (E). In this case, the energy is 5 joules.

2. Identify the charge (Q). In this case, the charge is 10 coulombs.

3. Divide the energy (E) by the charge (Q) to calculate the potential difference (V) in volts.

V = E / Q V = 5 J / 10 C V = 0.5 V

Therefore, the potential difference between the two power supply terminals is 0.5 volts.
