The potential differnce across the terminals of a 3 V battery is 3.6 V, when it is being charged by a current of 1.5 A. What is the internal resitance of the battery?

The potential difference across the terminals of a battery is 50 V when 11 A is drawn and 60V when 1A is drawn . The emf and the internal resistance of the battery are

The potential difference across the terminals of a battery is 8.4 V when there is a current of 1.50 A in the battery from the negative to the positive terminal. When the current is 3.50 A in, the reverse direction, the potential difference becomes 9.4 V. The internal resistance and e.m.f. battery are:

A galvanometer, together with an unknown resistance in series, is connected across two identical batteries of each 1.5 V. When the batteries are connected in series,the galvanometer records a current of 1 A, and when the batteries are connected in parallel, the current is 0.6 A. In this case, the internal resistance of the battery
