Question
When the switches are arranged so that the current through the battery is minimum, what is the voltage across points A and B -
Options
A.4 V
B.0 V
C.1 V
D.2 V
Solution
For minimum current, Resistance should be maximum so all switches must be open
So current through battery
= 2A
VAB = (1A) (1Ω) = 1V
So current through battery
= 2AVAB = (1A) (1Ω) = 1V
