Question

Why does resistance become more in series combination?

(a) Due to increase in area.

(b) Due to increase in length.

(c) Due to increase in length & decrease in area.

(d) None of these.​

Answer 1

Answer:

Resistance become more in series combination due to increase in length of the condutor. As in series combination we add the resistors in series so the length of wire increases . From this statement we can also say that

Resistance is directly proportional to the length of wire.

So the required option is (b) Due to increase in length .

:\implies
