AQA GCSE · Question 07.4 · Electricity
There is a potential difference of 3.6 V across the battery.
Calculate the energy transferred by the battery when 60 coulombs of charge flows through the battery.
Use the equation:
energy transferred = charge flow × potential difference
There is a potential difference of 3.6 V across the battery.
Calculate the energy transferred by the battery when 60 coulombs of charge flows through the battery.
Use the equation:
energy transferred = charge flow × potential difference
How to approach this question
1. Write down the equation provided: energy transferred = charge flow × potential difference.
2. Identify the values given: charge flow (Q) = 60 C and potential difference (V) = 3.6 V.
3. Substitute these values into the equation.
4. Calculate the result. The unit for energy is Joules (J).
Full Answer
energy transferred = charge flow × potential difference
energy transferred = 60 C × 3.6 V
energy transferred = 216 J
Potential difference (voltage) is defined as the energy transferred per unit of charge.
The equation is:
E = Q × V
Where:
- E is the energy transferred in joules (J)
- Q is the charge flow in coulombs (C)
- V is the potential difference in volts (V)
Given:
- Q = 60 C
- V = 3.6 V
Substituting the values:
E = 60 × 3.6
E = 216 J
