1.	The currents in the three branches of a parallel circuit are 3A, 4A and 5A. What is the current leaving it?(a) 0A(b) Insufficient data provided(c) The largest one among the three values(d) 12AI have been asked this question by my college director while I was bunking the class.My question is taken from Parallel Networks in portion Simple DC Networks of Basic Electrical Engineering
Answer» Right answer is (d) 12A For EXPLANATION I would SAY: The TOTAL CURRENT leaving a node is the same as the current that enters it. Total I=I1+I2+I3=3+4+5=12A.
