I have the circuit above.
When I have the switch at A, the capacitor C1 is charging at 100μF is at 10V.
I then discharge the capacitor by connecting the switch to B.
I was asked to calculate the time constant.
I thought the capacitors were in parallel but according to the answer, C1 and C2 are in series.
I calculated the time constant to be 20 seconds, but the answer was apparently 5 seconds as C1 and C2 were in series.
I attempted a similar question as shown below.
but they said that the total capacitance was 6.0μF where the capacitors were in parallel for part (i) which I can understand.
So who is correct for the first question?
T = CR
The Attempt at a Solution
Total C = 100 + 100 = 200μF
So T = 100x103 x 200x10-6 = 20 seconds.
