A battery has an open circuit potential difference of 6V between its terminal. when load resistance of 60 ohm is connected across the battery, the total power dissipated by the battery is 0.4W. a) find the internal resistance of the battery. b) Now the 60 ohm resistance is disconnected and a new load resistance R is connected across the terminals of the battery. What should be the load resistance R so that the maximum power will be dissipated in R c) Calculate its power. d) What is the total power supplied by the battery when such a load is connected ?
