WebKirchhoff law – problems and solutions by Alexsander San Lohat 1. If R1 = 2 Ω, R2 = 4 Ω, R3 = 6 Ω, determine the electric current flows in the circuit below. Known : Resistor 1 (R1) = 2 Ω Resistor 2 (R2) = 4 Ω Resistor 3 (R3) = 6 Ω Source of emf 1 (E1) = 9 V Source of emf 2 (E2) = 3 V Wanted: Electric current (I) Solution : WebPractice Questions 1. Calculate currents I_ {1} and I_ {2} in the given circuit? Solution: Let us identify the different nodes in the circuit as A and B. If the current entering the nodes are assumed positive, then 2 A – I1 = 0. Therefore, I1 = 2 A. Applying KCL at node B, we get the equation I1 + I2 = 0.
