How much energy is expended in moving a 20 coulomb charge through a potential difference of 0.5 volts?

The energy expended in moving a charge through a potential difference (voltage) can be calculated using the formula:

E = Q * V

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

Here are the steps to calculate the energy:

1. Identify the charge (Q). In this case, the charge is 20 coulombs.

2. Identify the potential difference (V). In this case, the potential difference is 0.5 volts.

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

E = Q * V E = 20 C * 0.5 V E = 10 J

Therefore, the energy expended in moving a 20 coulomb charge through a potential difference of 0.5 volts is 10 joules.
