Derive an expression for joule law of heating
WebJoule's Law of Heating: Let an electric current I is flowing through a resistor having resistance equal to R. The potential difference through the resistor is equal to V. The charge Q flows through the circuit for the time t. Thus, work done in moving of charge Q of potential difference V = V Q V = V Q http://astrowww.phys.uvic.ca/~tatum/thermod/thermod10.pdf
