Question

The potential difference across 8 ohm resistance is 48 volt as shownin the figure. The value of potential difference across `X` and `Y` point will be

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

Answer 1

Correct Answer - A
(a) The given circuit can be redrawn s follows
Resistane between `A` and `B = (24 xx 8)/(32) = 6 Omega`
Current between `(A)` and `(B)` = Current between `X` and `(Y)`
`= i= (48)/(6) = 8 A`
Resistance between `X` and `Y = (3 + 10 + 6 + 1) = 20 Omega`
`implies` Potential difference between `X` and `Y = 8 xx 20 = 160 V`
