Question

The potential difference across $8$ ohm resistance is $48$ volt as shown in the figure. The value of potential difference across $X$ and $Y$ points will be

• A. $128$ volt
• B. $160$ volt
• C. $80$ volt
• D. $62$ volt

Answer 1

The correct option is B $160$ volt

From given circuit we can say that

Resistance between $X$ and $Y=\frac{24\times 8}{32}=6\Omega$

Current between $X$ and $Y=$ Current between $X$ and $Y$

$=i=\frac{48}{6}=8A$

Resistance between $X$ and $Y=(3+10+6+1)=20\Omega$

$\Rightarrow$ Potential difference between $X$ and $Y=8\times 20=160V$
