Example Sheet 1 - Review of Components and calculations

1. Calculate the total impedance presented to the supply for the following circuits in both cartesian and polar form, assuming a 50 Hz supply:

2. For the circuits above, calculate the current flowing in polar form. in the circuit when connected to a 12 V, 50 Hz supply.

3. Considering circuit 1 (c) above, when the supply frequency increases, what happens to the phase and magnitude of the current?
