Question

Raj took a wire of length 10 cm. Ram took a wire of 5 cm of the same material and thickness. Both of them connected the wires as shown in the circuit given in Figure. The current flowing in both circuits is the same. The heating effect and resistance are likely to be more for ____

Answer 1

Answer:

i) Total sum of heat produced in the respective wire depends upon the length (end to end distance) of the wire. So, the total sum of heat produced in both cases will not be equal.

ii) No. Thickness or width of the respective wire decides the total sum of heat produced by the wire.

No, the amount of heat produced in the wire depends upon the thickness of the wire.
