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. WebThe molar conductivity of a solution at a given concentration is the conductance of the volume of solution containing one mole of electrolyte kept between two electrodes with the unit area of cross-section and distance of unit length.
