Worked Solution & Example Answer:A student uses a solar powered battery charger to charge some batteries - Edexcel - GCSE Physics - Question 4 - 2013 - Paper 1
Step 1
The diagram is an energy transfer diagram for a battery being charged.
Answer
The energy transfer can be explained in steps:
- Light energy from the sun strikes the solar cell and is converted into electrical energy.
- This electrical energy then transfers through the wires to the battery, where it is stored as chemical energy.
Thus, the completed energy transfer diagram should read:
light → electrical energy → chemical energy.
