Question

In an electric circut with a resistance wire and a cell, the current flowing is l What would
happen to this current it the wire is replaced by another thicker wire of same material and
same length ? Give reason.​

Answer 1

Answer:

On replacing the wire by a thicker wire the area of cross section increases. This will results into the more resistance since resistance is directly proportional to away of cross section.

Answer 2

Explanation:

the current I increases.

Explanation:

The resistance R of a conducting wire is given by the formula:

R=PL/A

where L = length of the conductor, A = cross sectional area

p = resistivity coefficient (constant

for a material)

Voltage connected across the resistance = V = constant

So IV/R=VA/ (PL)

If a thicker wire is connected instead of a thinner one, the A increases, and hence the current increases. Here Lis constant.
