The second principle for a parallel circuit is that all the currents through each resistor must add up to the total current in the circuit: \[I = I_{1} + I_{2} + I_{3}.\] Using these principles and our knowledge of how to calculate the equivalent resistance of parallel resistors, we can now approach some circuit problems involving parallel. For example, if a number of resistances, R1, R2, R3, etc. are connected in parallel, then their combined resistance R is given by the formula: 1/Req = 1/R1 + 1/R2 + 1/R3. Suppose that a resistance R1 of 4 ohms R2 of 6 ohms and third resistance R3 = 12 are connected in parallel and we want to find out their combined resistance R Parallel Circuit Calculations provides a comprehensive overview of the rules and formulas used to calculate electrical quantities and capacity. Using a direct current parallel circuit as an example, it explains the basic rules for electrical variables and how they relate. In a parallel circuit, voltage is the same across each branch. Current in a parallel circuit adds up to the total current. When V resistors of equal resistance R are connected in series, the equivalent resistance is 'nR'. i.e., R S = nR . The equivalent resistance in a series combination is greater than the highest of the individual resistances.
