Alternating Current questionWatch
Can anyone please explain?
We need to determine the energy transfer from the capacitor to the resistor between t1 and t2. To do so, we require the p.d transferred by the capacitor across the resistor between t1 and t2, and I dont understand how to calculate it.
Here we can throw conservation of energy at the problem - always a good start if you dont know what to do. If you know energy stored in the cap at the start and end times, then you can calculate a difference. You then have to work out where the energy went (it can't just vanish), did it go back through the bridge rectifier or into heating up the resistor ?
