Your switch is probably not what the OP intended. As you have it, there can never be 2V across the capacitor -- more like 20 mV. I suspect that what you really want is a SPDT switch that connects the capacitor to either R2 or R1. (more) |

Note that this process will define a *family* of solutions. A *specific* solution will depend on the phase of the AC source at the moment the connection is made, as well as the initial state of charge of the capacitor. (more) |

Most microwave ovens most conveniently offer operating times that are multiples of 10 seconds (or 30 seconds or one minute). So a turntable speed of 6 RPM is nice, in the sense that if you stick a mug of coffee or tea in the oven for a 30 seconds to re-warm it, the handle is pointing at you again whe... (more) |
