What is a shunt in electronics?

Microhm Electronics Ltd. is professional in SHUNTS for your diverse applications. A shunt is an element that is used in a circuit to redirect current around another part. The areas of application vary widely. For some applications, electrical devices other than resistors can be used. A few examples are given to illustrate the diversity of shunts. Shunt resistors, some time called ammeter shunt or Current shunt resistors, are low resistance precision resistors used to measure AC or DC electrical currents by the voltage drop t...

SMD Resistors Sizes and Packages

SMD Resistors Sizes and Packages

Resistors are available in different packages. The most popular ones at present are the rectangular surface mount resistors and axial resistor in through hole designs. The shape and size of surface mount resistors are standardized, most manufacturers use the JEDEC standards. The size of SMD resistors is indicated by a numerical code, such as 0201. This code contains the width and height of the package. So in the example of 0201 Imperial code, this indicates a length of 0.020 and a width of 0.010. This code can be given in Im...

How to Calculate the Equivalent Resistance Value for Resistors in Circuit?

How to Calculate the Equivalent Resistance Value for Resistors in Circuit?

Resistors are often connected inseriesor parallel to create more complex networks. An example of 3 resistors in parallel is shown in the picture below. The voltage across resistors in parallel is the same for each resistor. The current however, is in proportion to the resistance of each individual resistor. The equivalent resistance of several resistors in parallel is given by: The current through each resistor is given by: A designer might for example combine several resistors with standard values to reach a specific resist...

How to Test a Resistor

How to Test a Resistor

To check whether a resistor is good or not, we only need to check the resistors resistance value by using the ohmmeter of a multimeter. This is the best, easiest and most effective way . Take the ohmmeter and place its probes across the leads of the resistor and do not pay much attentio to the orientation as resistance isnt polarized. The resistance showing in the ohmmeter should be close to the rated resistance of the resistor. For example, when the resistance value of a resistors is 100Ω resistor with a tolerance rating ...

Resistors in LED Circuits

Resistors in LED Circuits

Resistors are widely used in automobiles, consumer electronics, computersand peripherals, communications, green energy, medicalinstruments, precision instruments and aerospace equipments. When used in LED circuits, an Light Emitting Diode (LED) emits light when an electric current passes through it. The simplest circuit to power an LED is a voltage source with a resistor and an LED in series. Such a resistor is often called a ballast resistor. The ballast resistor is used to limit the current through the LED and to prevent t...

Resistors Types and Materials Overview

Resistors Types and Materials Overview

Resistors can be divided in construction type as well as resistance material. The following breakdown for the type can be made: Fixed resistors Variable resistors, such as the: o Potentiometer o Rheostat o Trimpot Resistance dependent on a physical quantity: o Photo resistor(LDR) as a result of a changing light level o Thermistors(NTC andPTC) as a result of temperature change o Magneto resistor (MDR)as a result of a changing magnetic field o Varistor (VDR) as a result of a changing voltage o Strain Gauges as a result of mech...
