In the circuit given below, the voltage across AB is _______________(a) 250 V(b) 150 V(c) 325 V(d) 100 VThe question was asked in quiz.My doubt stems from Advanced Problems Involving Complex Circuit Diagram in division Network Theory and Complex Circuit Diagram of Network Theory

Answer»

Right ANSWER is (c) 325 V

The best I can EXPLAIN: Loop CURRENT I1 = \(\frac{50}{20}\) = 2.5 A

I2 = \(\frac{100}{20}\) = 5 A

VAB = (50) (2.5) + 100 + (5) (20)

 = 125 + 100 + 100

 = 325 V.
