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.

Can anyone please explain?

Vardhan95 gives you a nice hint. One of your key tools for attacking lots of very different physics problems is a conservation law, they come in different flavours, conservation of mass, momentum, angular momentum, spin, boson number etc.

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 ?
