cells can be connected in series ,in parallel and as well as combination of both the series and parallel .

Distinguish between Series and parallel circuit

Three wires each have resistance 2Omega , if we connect 2 in series with one parallel to the combination the equivalent resistance is

In parallel combination of n cells, we obtain

Two conducting wires of the same material and of equal length and equal diameters are first connected in series and then in parallel in an electric circuit. The ratio of the heat produced in series and parallel combinations would be :

When two identical cells are connected either in series or in parallel across a 4 ohm resistor, they send the same current through it. The internal resistance of the cell in ohm is

Two 220 V,100 W bulbs are connected first in series and then in parallel. Each time the combination is connected to a 220 V AC supply line. The power drawn by the combination in each case respectively will be :

Three capacitors of capacitances 1muF,2muF and 4muF are connected first in a series combination, and then in parallel combination. The ratio of their equivalent capacitances will be

Two 220 volt, 200 W bulbs are connected first in series and then in parallel. Each time the combination is connected to 220 V. The ratio of power drawn by the combination in respective cases is

A circuit consists of a resistance R connected to n similar cells. If the current in the circuit is the same whether the cells are connected in series or in parallel, then the internal resistancer of each cell is given by

Two similar condensers are connected in parallel and are charged to a potential V. Now these are separated out and are connected in series. Then
