Question

Which wire has greater resistance between a thick and thin wire of same length and same material

Answer 1

Heya FRIEND!!

Rajdeep here.....

First, let me tell you
..
..

That Resistance depends upon four factors:

1. Length of the wire: On increasing the length of the wire, the resistance also increases.

2. Area of cross section of the wire: With increase in the area of cross section, the resistance decreases.

3. Temperature of the wire: With increase in the temperature of the wire, the resistance increases.

4. Material of the wire: Good conductors have low resistance whereas bad conductors have high resistance.



Now, to answer your question,
Given that the two wires have:
1. Same length
2. Same Material
..
..


But....
One is thick and the other is thin.

The area of cross section of the thick wire is more;
The area of cross section of the thin wire is less;


Thus, it is clear that:
The thin wire has more resistance.
The thick wire has less resistance.

Thanks....

$\huge\mathrm{Answer}$

✪ Thick wire has lesser resistance whereas thin wire has more or greater resistance

✪ Reason :-

• Because in a thin wire the electrons does not get a large area of cross section to travel . As a result they collide among each other as a result resistance is maximum . Whereas the opposite happens for a thick wire . In a thick wire the electrons get enough space to move as a result resistance is minimum
