Question

Two wires A and B of the same material and having same length, have their cross sectional areas in the
ratio 1: 6. What would be the ratio of heat produced in these wires when same voltage is applied across
each?​

Answer 1

Answer:

6:1

Explanation:

R=ρl/A

Let Resistance of Conductor A be R and resistance of Conductor B be R'

Since, the material is same resistivity (ρ) is same.

Also, it is given that length is same.

R/R'=(ρl/A)/ρl/A'

R/R'=1/A/1/A'

R/R'=A'/A=1/6

R/R'=1/6

H/H'=(V²/Rt)/V²/R't

H/H'=6/1
