The resistance RRR of a copper "gauge 10" jumper cable with diameter d=0.259d=0.259 cmcm is 0.0124 ΩΩ. Find the length LLL of the cable. Express your answer in mm. Use three significant figures.

The length will be "3.89 m".

Explanation:

The given values are:

Diameter,

d = 0.259 cm

On converting it in m, we get

d = 0.259 × 10⁻²            

Resistance

R = 0.0124 Ω      

As we know,

⇒  

On putting the estimated values, we get

If,

then,

On substituting the values, we get

it is called kinetic energy
