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...

When trying to build a current monitor for a wireless sensor network, what kind of resistors shall i choose, high precision resistor s or current sense resistors ? Lets see the difference between them. Current sense resistors are generally low-value, high-power resistors. They are intended to develop a small voltage for a given current, so they are low in value. When used in power supplies they may well carry significant current and dissipate significant power, so they tend to be high-power units. For many applications they ...

A fixed resistor is the one having a fixed, defined electrical resistance which is not adjustable. Fixed resistors are the most commonly used resistors and in general one of the most used electronic components. Fixed resistors are available in surface mount packages and axial leaded as well as more customized packages depending on their application. Axial leaded resistors used to be the most popular one, but now SMD resistor s gain more market share. The followingresistor symbolsare often used to depict resistors with a fixe...

Ammeters are used to measure the AC or DC by measuring the voltage drop over a precision resistor with a known resistance. The current flow is calculated by usingOhms law. Most ammeters have an built-in resistor to measure the current. However, when the current is too high for the ammeter, the ammeter is placed in parallel with an accurate shunt resistor - ammeter shunt which is a high precision manganin resistor with a low resistance value. The current is divided over the shunt and the ammeter, so only a small percentage fl...

Resistance tolerance, TCR, resistance components distribution and other indicators do not exceed a certain standard. When the resistance value is above 1, tolerance is 0.5% generally. When it below 1, the tolerance is 1% normally. The tolerance of Microhms high precision resistors can be 0.05%, 0.1%.Precision resistors are widely used in aerospace, medical devices, automotive electronics, communication products and instrumentation because of their stable performance. Standards of precision resistors: 1. High precision 2.Low ...
