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.

Mutual Inductance Calculator - Inductances in Series Mutual Inductance Calculator - Parallel Inductances Resistor–Capacitor (RC) Circuit Calculator You may be interested in other calculators in the Electrical, RF and Electronics Calculators group: When combining several resistors in parallel, don’t forget to consider their tolerances and their power ratings and power dissipation. 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

The Resistor Colour Code system is all well and good but we need to understand how to apply it in order to get the correct value of the resistor.1 mΩ = 0.001 Ω.

The Standard Resistor Colour Code Chart : Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. High-power resistors that can dissipate many watts of electrical power as heat, may be used as part of motor controls, in power distribution systems, or as test loads for generators. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element.
