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
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
