1. Here's a pencil and paper. Tell me how a bridge rectifier with a capacitor-input filter works. In your explanation, I expect to see a schematic diagram and waveforms at different points in the circuit.
2. Suppose there's a bridge rectifier with a capacitor-input filter on my lab bench. It's not working. Tell me how you would troubleshoot it. Indicate the kind of instruments you would use and how you would isolate common troubles.
