I have attached the document which has the question and the diagram ----- A student is learning about how capacitors work. He uses the circuit shown in the attacment to investigate the capacitor C. Letter X labels a connection which he can make to either of the points L or M. Each cell has an e.m.f. of 1.5 V. He connects X to L. He sketches how the reading on ammeter 1 varies with time (Figure 2). Explain in terms of charge what has happened in the circuit. The answer is: Charging process (1) Plates oppositely charged OR charge moves from one plate to another (1) Charge flows anticlockwise OR electrons flow clockwise OR left plate becomes positive OR right plate becomes negative (1) Build up of Q/V reduces flow rate (1) I dont understand the last 2 points, can someone explain them please. How do we determine the direction of charge? And what do they mean with the capacitance building up.
