Worked Solution & Example Answer:A wind generator is used as the source of energy for a remote farmhouse - Edexcel - GCSE Physics - Question 3 - 2014 - Paper 1
Step 1
Complete the sentence by putting a cross (X) in the box next to your answer.
Answer
Given that the farmhouse is approximately 7 m high, it is reasonable to conclude that the height of the axle of the generator should be significantly taller to capture wind energy efficiently. Thus, the most suitable answer is:
X in box next to B (50 m).
Step 2
Complete the flow chart to show the energy transfers that take place from the wind to light a lamp.
Answer
The sequence of energy transfers can be represented as follows:
- Wind Energy: The kinetic energy from the wind turns the blades of the wind generator.
- Generator Energy: The mechanical energy from the rotating blades is converted into electrical energy by the generator.
- Lamp Light Energy: The electrical energy is then used to power the lamp, converting it into light energy.
