Calculate the equivalent resistance between A and B.(a) 2 ohm(b) 4 ohm(c) 6 ohm(d) 8 ohmThe question was asked by my school teacher while I was bunking the class.Query is from Series Circuits and Parallel Networks topic in section Simple DC Networks of Basic Electrical Engineering

Answer»

Right answer is (b) 4 ohm

The BEST explanation: R=((2+3)||5)+1.5)||4. The 2 and the 3 ohm resistor are in SERIES. The equivalent of these TWO RESISTORS is in parallel with the 5 ohm resistor. The equivalent of these three resistances is in series with the 1.5 ohm resistor. Finally, the equivalent of these resistances is in parallel with the 4 ohm resistor.
