Resistors one important parameter is electrical resistivity which is a measure of a materials property to oppose the flow of electric current. This is expressed in Ohm-meters (m). The symbol of resistivity is usually the Greek letter (rho). A high resistivity means that a material does not conduct well electric charge. Electrical resistance is expressed in Ohms, and is not the same as resistivity. While resistivity is a material property, resistance is the property of an object. The electrical resistance of a resistor is dete...

Microhm metal current sense resistors are popular devices used to measure current flow.Resistance value measurement tests typically use standard multimeters with two measuring wires. This measurement method is suitable for resistance values higher than 10 ohms, but is more prone to inaccurate results when measuring lower resistance values. This is especially true of current sense resistors with resistance values under 100 milliohms. Measuring resistance values less than 1 ohm requires the tester to apply a four-wire (Kelvin) ...

Chip resistors, small and ultrasmall in size, thin in terms of thickness, and lightweight, low inductance, have the characteristics of limiting DC or AC. Such characteristics are used to drop the voltage or maintain the current at a certain level inside an electronic circuit. Resistance basically follows the Ohms law. Materials of high and low electrical conductivities are used together to realize the required resistance value. Most widely used general chip resistors, they are made in various sizes ranging from 01005 to 4527 ...

Power resistors are usually larger than their lower power counterparts. The increased size helps to dissipate heat and often is used to provide mounting options for heatsinks. High power resistors are also often available in flame retardant packages to reduce the risk of a hazardous failure condition. The power rating of a resistor defines how much power a resistor can safely handle before the resistor begins to suffer permanent damage. The power dissipated by a resistor can be found easily using Joules first law, Power = Vol...

Current sense resistors are gaining in popularity due to their high measurement accuracy and relatively low cost compared to other technologies. An important element of a micro hybrid DC/DC converter application design includes measurement of the sensing voltage. Devices are used to sense input current continuously by measuring the voltage across a dedicated current sense resistor. Current sensing provides necessary precision channel-current balancing, and per-phase overcurrent protection. An optimal sensing voltage solution...

Many electrical devices are based on electrical resistance and Ohms law, even if they do not have little components in them that look like the usual resistor. Take voltmeter for instance. A voltmeter is nothing more than an ammeter with an additional high-value resistor through which the current is also forced to flow. Ohms law relates the current through the resistor to the voltage difference across it, so the meter can be calibrated in units of volts based on the known value of the resistor. The voltmeters two probes are to...
