Questions imageThe behaviour of the galvanometer needles in the previous experiment suggests that a current flows firstly one way, then the other as the switch is moved from O to P.

What does this suggest about the movement of charge in the circuit?
Equal amounts of charge flows off one plate and onto the other
More charge flows off plate A than plate B
More charge flows off plate B than plate A
No charge flows at all

Definitions imageWe say that the capacitor is charged up when connected to O and discharged when moved to P.
