The heat generated by the joule effect The work done on the carriers is Qv The work done on the carriers in unit time is QV The work done on the carriers in unit time and unit volume is VIV 732 JE=OE This is converted into the heat generated in unit time and unit volume due to the joule effect For a resistor carrying a current 1 the voltage acr ross it is IR, and the heat generated in unit time is IV=I(IR)=R
