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.
i) Use Figure 2 to state the potential difference between points B and C when the diode is in forward bias and is conducting.
ii) Calculate the potential difference between points A and B when the diode is conducting as in part i.
iii) Use Figure 2 to calculate the current in the power supply.
Sum EMF=Sum V around closed loop
Sum I in= Sum I out
1/R=1/R1 + 1/R2
I've tried doing it but i haven't been able to find the resistance of the diode.
