A zero-ohm resistor is a resistor that has almost no resistance at all; its resistance is near 0 ohms. A zero-ohm resistor can be wire wound or it can be surface mount. For wire wound resistors, there will be a single black color band around the body of the resistor. For surface mount resistors, there will be a 0 on it indicating it is a zero-ohm resistor. LMK series of Microhm Electronics include zero-ohm resistors, the actual value is less than 0.05m, rated current ranges from 0.5A to 2.5A. Zero-ohm resistors are available ...

In metrological applications, where accuracy is of paramount importance, highly precise standard resistors are also equipped with four terminals: two for carrying the measured current, and two for conveying the resistors voltage drop to the voltmeter. This way, the voltmeter only measures voltage dropped across the precision resistance itself, without any stray voltages dropped across current-carrying wires or wire-to-terminal connection resistances. Microhm Electronicss MVR2321-4, shunt resistor MMS4026 are typical and popul...

Power management has evolved as electronics continually are miniaturized and deployed in an increasing array of applications. Since there are so many types of specialized circuits with unique operating voltages, it has become commonplace to provide a single external voltage level to a device and to rely on conversion within the device to provide the appropriate power levels to each load. For example, a device may have nine loads and require five voltages, which can be provided by incorporating DC-DC converters. Microhm Elect...

Renewable power is not a recent phenomenon. Hydroelectric plants have been popular in some areas for many decades. Power from these renewable sources differs from conventional sources, such as coal, gas, and nuclear plants. This is because renewables either generate dc power directly, or the power they generate requires some conversion between ac and dc and back. Carbon-based generation inherently produces ac power, which can easily be fed into the grid using substation transformers. As an important passive component, resisto...

Ammeter shunt resistor operation is well-understood. Used extensively for current measurement in the past, the resistors are used to shunt most of the current around the measurement instrument. This technique allows measurement of greater currents than is possible using normal ammeters. The low-value resistor is situated in series with the load, creating a small voltage drop across the resistor, which can be measured using a voltmeter. The current is then calculated using Ohms law. Modern ammeter shunts are a bit more complex...
