Two tungsten bulbs of wattage 100 W and 60 W power work on 220 V potential difference. If they are connected is parallal,how much current will flow in the main conductor?

A potentiometer wire is 100 cm long hand a constant potential difference is maintained across it. Two cells are connected in series first to support one another and then in opposite direction. The balance points are obatined at 50 cm and 10 cm from the positive end of the wire in the two cases. The ratio of emfs is:

Solve the following examples/ numerical problems. A potential differnce of 250 volts is applied across a resistance of 1000 ohm in an electric iron. Find (1) the current (2) the heat produced in joule in 12 seconds. Keeping other conditions the same, if the length of the wire in the iron is reduced to half the original length ( by cutting the wire), what will be the current and heat produced?

The resistance of a conductor is 10 ohm. Find the current through it when a potential difference of 2 V is applied across it. To pass the same current through a conductor of resistance 40 Omega , how much potential difference should be applied across it?
