Could you please explain Q2 iii

2 Components can be connected in a circuit in series, and in parallel. a Figure 2 shows an electrical circuit. The resistors and the (silicon) diode are connected to a power supply of negligible internal resistance. Power supply = 6 V R. = 300Q RX = 330 0 Ra = 100 g R1 D1 Ra Figure 2 Use Figure 2 to state the potential difference between points B and C when the diode is in forward bias and is conducting. potential difference =. - unit = =------- (1 mark) ii Calculate the potential difference between points A and B when the diode is conducting as in part i. potential difference = ..--- ..-. unit = ...----- (1 mark) iii Use Figure 2 to calculate the current in the power supply. urrent : \\
