Assertion:In the part of a circuit shown in figure, given that V_(b) gt V_(a) . The current should flow from b to a. Reason: Direction of current inside a battry is always from negative terminal to positive terminal.

Two identical capacitors are connected in the circuit shown. C_(2) is charged to 100 V and switch S is shifted from position 1 to position 2 . The negative terminal of C_(2) is connected with the positive terminal of C_(1) . Find the work done by the battery. If the polarity of C_(2) were reversed, what work would have been done by the battery ?

How much work is required to carry a 6muC charge from the negative terminal to the positive terminal of a 9 V battery?

The potential difference across the terminals of a battery is 10 V when there is a current of 3 A in the battery from the negative to the positive terminal. When the current is 2A in the reverse direction, the potential difference becomes 15 V. The internal resistance of the battery is

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 Air , the reverse direction, the potential difference becomes 9.4 V . (a) What is the internal resistance of the battery? (b) What is the emf of the battery?

n' cells , each of emf 'e' and internal resistance 'r' are connected in a closed circuit so that the positive terminal of a cell is joined to the negative terminal of the next, as shown in figure. Any two points of the circuit are connected by an external resistance R. Find the current in R.
