The combination is V volts, and I is the total current through the combination.

Namely R 1, R 2, R 3,…R N connected in series as shown in Figure-1. In order to understand the calculation of equivalent resistance in series, consider N-resistor Resistors, or simply resistors in series. Provides only one path for the flow of electric current, it is called series connection of
PARALLEL RESISTANCE FORMULA HOW TO
How to Calculate Equivalent Resistance in Series?Ī combination of resistors in which they are connected end-to-end in a chain fashion, and We will also discuss the numerical examples on each of the three combinations forīetter understanding of the concept. In this tutorial, we will understand what the equivalent resistance is, how to determine theĮquivalent resistance of resistors when they are connected in series or parallel or series and For this reason, we connect two or more resistor in a particular manner to obtain a desired resistance in the circuit. Sometimes, we do not have a resistor of desired resistance that is required in the circuit. The resistor is a passive circuit element that controls the flow of current through a circuit, and coverts the extra amount of electrical energy into heat. The electric circuit element that is used to introduce the electrical resistance in the circuit is called resistor. The Unit Conversion page provides a solution for engineers, translators, and for anyone whose activities require working with quantities measured in different units.In electrical and electronic circuits, resistance or electrical resistance is defined as the amount of friction in the flow of electric current (or electric charge) offered by the conductor material. This online unit converter allows quick and accurate conversion between many units of measure, from one system to another. In this part of the Unit Converter, we present a group of calculators related to various aspects of electrical engineering, electronics, and RF engineering. Examples of such devices are mobile phones, routers, computers, two-way radios, credit cards, satellite receivers, televisions, and other equipment that transmits and receive radio waves. Radio-frequency engineering (RF engineering) is a field of engineering that deals with devices that transmit or receive radio waves in the radio frequency spectrum (3 kHz to 300 GHz). Internal Resistance of a Battery CalculatorĮlectrical, RF and Electronics CalculatorsĮlectronics is a branch of physics, electrical engineering, and technology concerned with the design and use of electrical circuits containing active electrical components (diodes, transistors, and integrated circuits) and passive electrical components (resistors, inductors, and capacitors) and connections between them.

However, the currents flowing through individual resistors are different and depend on their resistance the total current for the group is the sum of the currents through individual resistors. Note also that all resistors connected in parallel have the same voltage across their ends. Note that for a group containing any number of resistors connected in parallel, the equivalent resistance is always less than the smallest resistor in the group of resistors and adding any new resistor will always decrease the equivalent resistance of the group. If there are n equal resistors R connected in parallel, then the equivalent resistance For example, three resistors, 10, 15 and 20 ohms connected in parallel will produce 4.62 Ω: This formula for R eq is used for the calculation in this calculator. The equivalent resistance R eq of a group of resistors connected in parallel is the reciprocal of the sum of the reciprocals of the individual resistors:Įlectrical conductance G is reciprocal to resistance, therefore the equivalent conductance G of a group of resistors connected in parallel is defined as
