Question

A current of $15 \,mA$ flows in the circuit as shown in figure. The value of potential difference between the points $A$ and $B$ will be

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

Answer 1

Answer: (D)

$ i _1=\frac{5}{10+5} \times 15 \,mA =5\, mA $
$ V _{ A }-5 i -10 i _1-10 i = V _{ B } $
$ V _{ A }- V _{ B }=75+50+150=275 \,V$
