Question

write the relation between heat and current?​

Answer 1

Answer:

Heat is indirectly proportional to current :-) may be

Answer 2

HELLO MATE

The wire carries the same current as the heater (because they are connected in series), but has a much lower R, so by I2R generates less heat.

The series connection of heater and wire means that the incoming 240v is split between them. In the case of a nominally 10A heater, the resistance will be 24ohms. If the wire has a resistance of 0.024ohms (reasonable), then the 10A through the wire will result in a voltage drop of 0.24v, and so 2.4 watts generated in the wire. This will leave the wire so cool you'd barely notice it. The remaining 239.76 volts across the heater will give you 2397.6w rather than 2.4kW.
