How many calories of thermal energy will be generated if the electromotive force of an electric cell is 6 volt and the internal resistance is 2 ohm . and when the electric cell is connected to a resistance of 8 ohm and it flows for 21 seconds ? please answer this question​

Answer»

Total 10 ohms in series .VOLTAGE = 6V.POWER = VXV/R = 36/10=3.6 wattsEnergy = Power X Time .Time = 21 sec.Energy in Joules = 21X3.6 = 75.8 Joules = 0.01811663 X 1000 Calories.= 181.1663 Calorieshope it will be HELPFUL : )
