Question

how do u work out energy transfer over a certain time?..formula?

Answer 1

You need to be a little more specific. This is pretty much what heat transfer classes are devoted to.

Answer 2

Resistor2 = 2
and it says...calculate the energy transferred in R2 in 2 mins

Answer 3

Power dissipated in a circuit is\[P=IV=V^2/R=I^2R\]Use whichever form of this equation that you have enough information for. The energy will be the power time the time (watch your units)

Answer 4

thank u =)
