What is the relationship between potential difference and energy transferred in a circuit?.
- A.Potential difference is the energy supplied per unit charge.
- B.Potential difference is the energy lost per unit charge.
- C.Potential difference is the total energy in the circuit.
- D.Potential difference is the rate of energy transfer.
Model answer
What a good answer should say
- Potential difference is the energy supplied per unit charge.
Explanation
Why this works
This statement is correct because potential difference (V) is defined as the energy (E) transferred per unit charge (Q), represented by the formula V = E/Q.
