    Input Voltage
AI Thread Summary
The discussion centers on a circuit that can double input voltage, with participants suggesting that understanding AC voltage sources, diodes, and capacitors is essential for analysis. There's a suggestion to move the question to a homework section for quicker assistance, emphasizing the importance of effort from the original poster (OP). Key points include the need to analyze the voltage waveform on C2 and the significance of D1's conduction in transferring potential to C2. Participants encourage the OP to demonstrate their current understanding to facilitate better guidance. Overall, the conversation highlights the collaborative nature of learning in physics.

Is this a homework question? If you know how AC voltage sources, diodes and capacitors all work then the answer should be obvious to you.
 
Move it to the homework section under intro physics and it will be answered in an hour or so...

I don't think anyone on this forum is into the habit of doing homework for other people. There is an INCREDIBLE amount of help available if the OP is willing to put forth effort.
 
Some suggestions:
a)
Before trying to analyze the circuit think first how voltage wave-form on C2 must look like (Doubling the voltage does not mean that waveform of source and Vout are identical)
b)
Pay attention to point "2" of the circuit.That's crucial.When D1 conducts it's potential is effectively transferred to the bottom of C2.
 
Thread moved to the homework forums. Duncan, please show us your work so far.
