Question

Ravi took a wire of length 10 cm. Rahim 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 the circuits is
the same.

(i) Will the heat produced in both cases be equal? Explain. (1 mark)
(ii) Will the heat produced be the same if the wires taken by them are of equal lengths but of different
thicknesses? Explain. (1 mark)
(iii) In addition, what can you use in the circuit to find out that current is flowing through the circuit? ( 1
mark)

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.

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