2 23 A block of metal is heated directly by dissipating power in the internal resistance of block Because of temperature rise the with resistance increases exponentially time and is given by R t 0 5 e2t where t is in second The block is connected across a 110 V source and dissipates 7644 J heat energy over a certain period of time This period of time is 10 sec take In M
