Consider two arrangements of N identical resistors one in parallel and the other in series. Each of these arrangements are connected to batteries of the same voltage. The ratio of power dissipated in the parallel arrangement to the series arrangement is:

Electircal appliances are connected in parallel. What are the advantages of this arrangement ?

Two resistors whose value are in ratio 2 : 1 are connected in parallel with one cell. Then ratio of power dissipated is

Three equal resistors connected in series across a source emf together dissipate 4 watt.If the same resistors are connected in parallel across the same emf the power dissipate will be

The equivalent resistance of n identical resistors connected in parallel si x . If the resistors are connected in series, the equivalent resistance would be.

When cells are arranged in series

Three equal resistor connected in series across a source of enf together dissipate 10 Watt . If the same resistors aer connected in parallel across the same emf, then the power dissipated will be

Two identical resistor each of resistance 10 Omega are connected in (i)series and then (ii) in parallel in line to a battery of 6 volts. Calculate the ratio of power consumed in the combination of resistor in the two case.

A 2.0 mu F capacitor and a 4.0 mu F , capacitor are connected in parallel across in 300V potential difference (a) What is the total energy stored by them? (b) They are next connected in series across that potential difference. What is the ratio of the total energy stored by them in the parallel arrangement to that in the series arrangement?
