Question:

charging capacitor & inductor any ideas?

can anyone give out any ideas of what happens upon switch is closed rather than just charging ? any ideas would be greatly appreciated. here's the diagram

Answer:

a) in position A, the C will charge up towards 8 volts with a time constant of 560 x 22u 12 ms. After 5 or so time constants, it will be very close to 8 volts. In position B it will discharge towards ground with a time constant of 820 X 22u or 18 ms. After a while it will be close to zero volts. .
