Question

A current of $15 \,mA$ flows in the circuit asshown in figure The value of potentialdifference between the points $A$ and $B$ will be

• A. 50 V
• B. 75 V
• C. 150 V
• D. 275 V

Answer 1

Answer: (D)

275 V

Answer 2

The correct answer is (D) : 275 V

i1​=10+55​×15mA=5mA
VA​−5i−10i1​−10i=VB​
VA​−VB​=75+50+150=275V
