Calculate the potential difference if 20J of energy are transferred by 8C of charge.

1. Break Down the Problem

We need to calculate the potential difference (V) given:

• Energy (E) = 20 Joules (J)
• Charge (Q) = 8 Coulombs (C)

2. Relevant Concepts

The formula for potential difference is given by: $V = \frac{E}{Q}$ where:

• $V$ is the potential difference in volts (V),
• $E$ is the energy in joules (J),
• $Q$ is the charge in coulombs (C).

3. Analysis and Detail

Substituting the values into the formula: $V = \frac{20 \, \text{J}}{8 \, \text{C}}$

Calculating the potential difference: $V = \frac{20}{8} = 2.5 \, \text{V}$

4. Verify and Summarize

We've applied the formula correctly and calculated step-by-step to ensure accuracy. The potential difference calculated confirms this.

Final Answer

The potential difference is $2.5 \, \text{V}$.
