a. Explain with the aid of diagrams, the operation of the circuit with the switch first in position 1, and then in position 2. b. Calculate the total current supplied to the circuit 65ms after the switch is moved to position 1. c. The time taken for the voltage across the coil to reach 75% of its initial value. d. The time taken for the coil to become fully energised. e. Calculate the peak voltage at the instant the switch is moved to position 2 (assuming steady state conditions have been achieved before switching). f. The potential difference across the 500 resistor after 20ms. g. Calculate the time taken for the coil current to fall to 20% of its normal running value after the switch is moved to position 2 (assuming steady state conditions have been achieved before switching).
