For the circuit below , find the voltage across 5Ω resistor and the current through it.(a) 1.93 V(b) 2.83 V(c) 3.5 V(d) 5.7 VThe question was asked in an internship interview.The above asked question is from Kirchhoff’s Current Law in division Circuit Elements and Kirchhoff’s Laws of Network Theory

Answer»

Correct option is (B) 2.83 V

Easy explanation: Here all the resistors are connected in PARALLEL and let the voltage be V. Hence, i15=V/15, i5=V/5, i2=V/2, i1=V/1. By kirchhoff’s CURRENT law, V/15 + V/5 + V/2 V/1 +5 = 10. On solving EQUATION, we obtain the value of V. As all resistors are in parallel, voltage across each is same as V.
