Application +4 | -1

Two wires

A

and

B

made of same material and having their lengths in the ratio

6: 1

are connected in series. The potential difference across the wires are

3 \mathrm{~V}

and

2 \mathrm{~V}

respectively. If

r_A

and

r_B

are the radii of

A

and

B

respectively, then

\frac{r_B}{r_A}

View answer and explanation

Correct option: B

\frac{1}{2}

Option B (

\frac{1}{2}

) is correct because the ratio of radii is calculated using the relationship between potential difference, length, and resistance, considering the wires are made of the same material.
