1.	compute the heat energy produced in an electric circuit if a 5ohm resister draws a current of 2amphere in 0.5 seconds
Answer» oduced , H=I2Rthere, tH5=I52R5=10⇒I5=510=2 . This is the CURRENT through resistor 5Ω.Voltage across resistor 5Ω is V5=I5R5=2×5=52VAs RESISTORS (4,6) and 5 are in parallel, so potential across (4,6) is EQUAL to V5.As resistor 4 and 6 are in series so current through each resistor I4=I6=4+6V5=4+652=22Heat produce in resistor 4 per sec =I42R4=(22)2×(4)=2cal/sec
