RESISTANCE PHYSICS CALCULATOR SERIES

You can calculate up to ten resistors that are connected either in series or parallel using this user-friendly online free series and parallel resistance calculator. For example, for lighting circuits, we use the parallel connection, while for appliances that work directly on mains, a series connection is given.ĬalculatorHut, a one-stop destination of online scientific and non-scientific calculators, offers free online series and parallel resistance calculator that will solve all your online calculator needs for free. We come across the arrangement of series and parallel combination of resistors in many places in our day to day life. How does CalculatorHut’s series and parallel resistance calculator helps you? In a parallel resistors circuit, if one resistor is damaged, the current keeps flowing in the other resistors and the circuit will keep working, however with a different value of net resistance.In a series resistors circuit, if one resistance gets damaged, the entire circuit will break and behave as an open circuit.The current in each of the series connected resistor is the same, while the voltage across each parallel resistor is the same.

The effective resistance of a parallel circuit is always lesser than each of the resistor in the circuit.

The effective resistance of a series circuit is always greater than each of the resistor in the circuit.

Points about series and parallel connection of resistors: If you find a circuit that has resistors in series and parallel, then you have to solve the resistors combination step by step considering whether they are in series or parallel with the neighboring ones and then arrive at the final resistance of the circuit. Observe that if you add the individual currents through each resistor, you will get the total current that is flowing in the circuit.Ĭombination of Series and Parallel Resistors In case you want to calculate current in each resistor, you can use Ohm's law:Ĭurrent through 4 ohms resistor I 1= 10/4 = 2.5 AĬurrent through 8 ohms resistor I 1= 10/8 = 1.25 AĬurrent through 4 ohms resistor I 1= 10/8 = 1.25 A Then the current flowing through the circuit is given by V/I = 10/2 = 5 amps. In general, if ‘n’ resistances are connected in parallel, the net resistance is:ġ/ R net = 1 / R = 1 / R + 1 / R 2 + 1 / R 3 +….+ 1/R nįor example, if three resistors 4ohms, 8 ohms and 8 ohms are connected in parallel in a circuit with 10 V supply, then, the net resistance of the circuit is given by: 1/Rnet = 1/4+1/8 + 1/8 = ½ or Rnet = 2 ohms The net resistance of this parallel circuit is 1/R net = 1 / R = 1 / R 1 + 1 / R 2 + 1 / R 3.

The following circuit diagram shows three resistances R 1, R 2 and R 3 connected in parallel. When resistances are connected in parallel, the inverse of the net resistance of the circuit is the sum of inverses of all the resistances of the circuit.

In a parallel circuit, the current originating from the source or the total current will branch up at the junction where the heads of resistances meet and then flows in different quantity in each resistor and then again combines together at the meeting point of the tails of the resistors and flows towards the origin. Two or more resistors are said to be connected in parallel if they are joined with their heads on one side and tails on the other side of the circuit.
