Draw a circuit diagram when three bulbs are connected in series with a battery of cells, which are also connected in series.

Battery is a collection of cells connected in

Which electrical elements are connected in series ?

Draw a circuit diagram for series and parallel circuit with three bulbs.

Two bulbs, when connected in series, are brighter than a single bulb.

(a) Resistors given as R_(1), R_(2) and R_(3) are connected in series to a battery V. Draw the circuit diagram showing the arrangement. Derive an expression for the equivalent resistance of the combination. (b) If R_(1)=10 Omega, R_(2)=20 Omega and R_(3)=30 Omega , calculate the effective resistance when they are connected in series to a battery of 6 V. Also find the current flowing in the circuit.

Twelve cells each having the same emf are connected in series and are kept in a closed box. Some of the cells are wrongly connected. This battery of cells is connected in series with an ammeter and two cells identical with the others. The current is 3A when the cells and the battery aid each other and is 2A when the cells and the battery oppose each other. How many cells in the batter are wrongly connected?

Three capacitors of capacitances 2 muF , 3mu F and 6muF are connected in series with a 12 V battery. All the connecting wire are disconnected, the three positive plates are connected together and the three negative plates are connected together. Find the charges on the three capacitors after the reconnection.

Draw a circuit diagram for a bulb connected to a cell with a switch. Mark arrows in the diagram to indicate the direction of flow of current.

Three bulbs of 40 W , 60 W and 100 W are connected in series with a 240 V source.

When three identical bulbs are connected in series. The consumed power is 10W. If they are now connected in pa rallel then the consumed power will be:-
