Sum of resistance in parallel
WebThe equivalent resistance of a number of resistors in series is equal to the sum of their individual resistances. When a number of circuit elements are connected in parallel current paths, so that the voltage across each of them is the same, they are connected in parallel. By Kirchhoff's current rule, at a junction at one end of the parallel ... Web1) A parallel circuit has two or more paths for current to flow through and the total current is equal to sum of currents flowing through these paths. 2) Voltage is same across each component of parallel circuit. 3) The current in all the branches is same. As shown in the figure: C. The effective resistance in the above circuit is given as:
