A battery has an open circuit potential difference of 6V between its terminals. When a load resistance of 60Ω is connected across the battery,the total power supplied by the bttery is 0.4W. What should be the load resistance R, so that maximum power will be dissipated in R. Calculated this power. What is the total power supplied by the battery when such a load is connected?
