The Unit Conversion page provides a solution for engineers, translators, and for anyone whose activities require working with quantities measured in different units. ![]() 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. Total Harmonic Distortion (THD) Calculator Three-Phase AC Power Calculator (Balanced Load) The calculator-online gives basic to advance level physics calculators that will assists you to solve the different complex problems. Radar Horizon and Target Visibility Calculator Don’t fret, our free online physics calculators helps to calculate the different physics related terms. Radar Maximum Unambiguous Range and Pulse Repetition Frequency Calculator Calculation of Current-Limiting Resistors for a Single LED and LED Arrays NFC/RFID Planar Spiral Coil Inductance Calculator Parallel RLC Circuit Impedance Calculator Mutual Inductance Calculator - Inductances in Series Mutual Inductance Calculator - Parallel Inductances the Resistance Due To Temperature Calculator The following Physics tutorials. Resistor–Capacitor (RC) Circuit Calculator Our wire resistance calculator uses the following resistance formula: R. 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 Rod? (e) Discuss why the actual experiment used a rotating spool of thin wire rather than a moving bar as in our simplified analysis.1 mΩ = 0.001 Ω. A cylindrical column of mercury is in a vertical glass tube. $(25.6)$ only if the coefficient of thermal expansion is small. $(25.12)$ equals the temperature coefficient of resistivity $\alpha$ in Eq. The temperature coefficient of resistance $\alpha$ in Eq.
