Which of the two has greater resistance : a 1kW heater or a 100W tungsten bulb, bath marked for 230V?

Which has greater resistance : 1 kW electroheater or a 110 W filament bulb, both marked for 220V?

Which has more resistance : 100 W bulb or 60 W bulb ?

Which one is having more resistance,100 W bulb or a 50 W bulb?

A boy has two spare light bulbs in his drawer. One is market 220V and 100W and the other is market 240V and 60W. He tries to decide which of the following assertions are correct?

Calculate the resistance of an electric heater of 1 kW if it operates on a 220 V power supply.

Out of the two, a toaster of 1 kW and an electric heater of 2 kW , which has a greater resistance ?

A nichrome heating element across 230 V supply cosumes 1.5 kW power and heats upto a temperature of 750^@C . A tungsten bulb across the same supply operates at a much higher temperature of 1600^@C in order to be able to emit light. Does it mean that tungsten bulb necessarily cosumes greater power ?

Two bulbs ar marked (a) 100 W, 220 V(b) 40 W, 220 V.Which has higher resistance ? Also calculate the maximum current that can flow through each bulb.
