Best Battery Saving Tips - Get Amazing Battery Life on Your Phone

The internal resistance of an accumulator battery of emf 6V is 10(Omega) when it is fully discharged,As the battery gets charged up.its internal resistance decreases to 1(Omega) The battery in its completely discharged state is connected to a charger which maintains a constant potential difference of 9 V.Find the current through the battery (a)just after the connections are made and (b) after a long time when it is completely charged.

A battery of emf E has an internal resistance r. A variable resistacne R is connected to the terminals of the battery. A current i is drawn from the battery. V is the terminal potential difference. If R alone is gradually reduced to zero, which of the following best describes i and V?

Motorcycle is related to Battery in the same way as Life is related to 1)Earth 2)Sun 3)Moon 4) Star 5)None of these

Two capacitors A and B are connected in series with a battery as shown in the figure. When the switch S is closed and the two capacitors get charged fully, then
