Define the terms 'charging' and 'discharging' in the context of capacitors. What is the key difference between the two processes?.
Model answer
What a good answer should say
- Charging refers to the process where a capacitor accumulates electric charge, increasing its potential difference.
- Discharging is when the stored charge is released, causing the potential difference to decrease.
- The key difference is that charging involves energy being supplied to the capacitor, while discharging involves energy being released from the capacitor.
Explanation
Why this works
This question tests the understanding of capacitor behavior during charging and discharging processes, which are fundamental concepts in electricity. It requires students to define both terms and identify their key difference, demonstrating their grasp of how capacitors function in circuits.
