Parallel and series resistor calculator
How do you add resistors in series and parallel?
Tips Remember, when resistors are in parallel, there are many different means to an end, so the total resistance will be smaller than each pathway. When resistors are in series, the current will have to travel through each resistor, so the individual resistors will add to give the total resistance for the series.
How do you calculate resistors in series?
To calculate the total overall resistance of a number of resistors connected in this way you add up the individual resistances. This is done using the following formula: Rtotal = R1 + R2 +R3 and so on. Example: To calculate the total resistance for these three resistors in series.
How to calculate resistors in parallel?
The equation for combining n resistors in parallel is: R eq = 1/ { (1/R 1 )+ (1/R 2 )+ (1/R 3 )..+ (1/R n )} Here is an example, given R 1 = 20 Ω, R 2 = 30 Ω, and R 3 = 30 Ω. The total equivalent resistance for all 3 resistors in parallel is: R eq = 1/ { (1/20)+ (1/30)+ (1/30)} = 1/ { (3/60)+ (2/60)+ (2/60)} = 1/ (7/60)=60/7 Ω = ...
How do you calculate the total resistance of a parallel circuit?
The total resistance for the parallel circuit must be less than the resistance of any individual branch. Resistance is measured in ohms. Calculate the total resistance by dividing the total current from the voltage; this equation, I = V/R, is known as Ohm’s Law.

The inductor behaves identically to the resistor in terms of series and parallel combinations. That is, the equivalent of a series connection of inductors is simply the sum of the values. For a parallel connection of inductors either the product-sum rule or the “reciprocal of the sum of the reciprocals” rule may be used.
