Analysing effects of varying the component parameters of a power circuit.

Thread Starter

I'm currently studying an electrical engineering BTEC and i'm having trouble completing one of the assignment tasks. It involves a AC power circuit with diodes, capacitors and a transformer. I need to report on the effects of varying the values of the: transformer turns ratio, capacitor value, and load resistor. I have created the circuit in multisim and connected an oscilloscope.

Any help would be greatly appreciated.

Since this is homework, you need to show your best effort before asking members to try to guide you to a solution.

What happens when you change the turns ratio of a transformer?
What do the diodes to?
What is the purpose of the output capacitor?
When you have the answer to those questions, you can answer some of your other questions.
