Answer:

Q-Two bulbs whose resistances are in the ratio 1:2 are connected in parallel to a source of constant voltage. What will be the ratio of power dissipation in these bulbs power dissipation in these bulbs Q. Two wires A and B of the same material and having same length, have their cross-sectional areas in the ratio 1: 4. What would be the ratio of heat produced in these wires when same voltage is applied across each? CBSE Sample Paper 1997) Q. Which has a greater resistance-50W electric heater or a 100 W filament bulb both marked for 220 V?
