Hi
I have been told that the question below might be similar to potential university interview questions for physics/electronic engineering.
In relation to this circuit diagram:
Initially 240V rms mains voltage is connected between terminals A and B in the circuit above. You can assume that the capacitors and diodes are appropriately rated to work at this voltage.
When the capacitors have ceased to charge, the mains voltage is disconnected.
What voltage will then be measured between points C and D?
To my mind the voltage between C and D will just be the sum of the voltages across the two capacitors but C1 will not charge so the 240V rms will be all across C2. This will result in the voltage between C and D to be 240V.
