Question

The current through the $8\Omega$ resistor (shown in figure) is :

• A. $4A$
• B. $2A$
• C. $0A$
• D. $2.5A$

Answer 1

The correct option is C $0A$

Both pair of pair batteries which are connected nearby are of same magnitude but opposite polarity hence they will cancel the effect of each other or current by each other hence there will be no current in the circuit because there no any battery who is independent and not compromised.

Hence we can say that the batteries will cancel each other's effect and finally there will be no current anywhere in the circuit
