Answer 1

Answer:

Given that

R = 6 Ohms

\(R = \frac{\rho l}{A}\)————-(1)

Wire is doubled so, Area (A) = 2A

length (l) = l/2

New Resistance will be:

\(R_{new} = \frac{\rho (\frac{l}{2})}{2A}\)

Rnew = ρl/4A

By using eqaution (1) we can simplify the above equation as

Rnew = R/4

Rnew = 6/4

Rnew = 1.5 Ohms

Hence, the new Resistance of wire is 1.5 Ohms.
