Question

If you create a wire twice as thick, how does the resistance of the wire change?

Answer 1

Hint : Resistance may be a measure of the opposition to current flow in a circuit . Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the connection between voltage, current and resistance.

Complete Step By Step Answer:
The resistance is directly proportional to the length of the conductor and inversely proportional to the cross sectional area of the conductor. Doubling the length doubles the resistance. Hence, if the length of a wire is doubled, then its resistance becomes 2 times.
The resistance of any conductor is decided by the straightforward arithmetic relationship R = RL/A, where R is that the resistance, r may be a constant number representative of the sort of fabric being stretched, L is that the wire length, and A is that the cross sectional area of the wire.
During this relationship R is directly proportional to r and L but inversely proportional A. this is often a simplistic way of claiming that if we double L the resistance doubles assuming nothing else changes, but if we double the world simultaneously the resistance of the wire wouldn't change. R = r2L/2A.

Note :
The subsequent are the most laws of resistance: (i) Resistance of a conductor is directly proportional to its length, provided temperature and other physical conditions remain unchanged. (ii) Resistance of a conductor is inversely proportional to its area of cross section, other conditions remaining an equivalent.
