Condensers of capacities 5F and 10F are connected in parallel in a circuit with a cell of e.m.f. 2V. The capacity of the condenser to be connected in series with parallel combination of the condensers to get 1C charge to flow in the circuit is

Two long parallel wires are hanging freely. If they are connected to a battery (i) in series, (ii) in parallel, what would be the effect on their positions?

Observe the circuit and state whether the cells are connected in series or parallel. If each cell is of e.m.f. 1.5 V , then find the total e.m.f applied across the bulb connected.

N batteries each of emf E and internal resistance r are first connected in series and then in parallel to an external resistance R. if current through R is same in both cases then.

A battery of electro motive force E is connected in series with a resistance R and a voltmeter. An ammeter is connected in parallel with the battery.
