IntroductionWhat is a resistor?The resistor is a passive electrical component to create resistance when electric current flowing. We can find it in all electrical networks and electronic circuits. The resistance is measured in ohms. An ohm is the resistance that occurs when a current of current passes through a resistor with a one volt drop across its terminals. Commonly used color band resistor can be divided into four-band and five-band, in practice, usually four-band. The front two bands ...

A team of MIT engineers has described a novel way of controlling the flow of water in flexible tubes, a finding with implications for agricultural systems worldwide. Their research, published in the Journal of Mechanical Design, could reduce the energy demands of pulsating sprinklers used for irrigation."Food and its relationship to water is one of the biggest problems in the world," says Ruo-Qian Wang, a former postdoc at the MIT Tata Center for Technology and Design who is now a post ...
TT Electronics launched the LCS series of thin film resistors. For sensing and measurement of DC and AC currents in the sub-3A range, the resistors bring precision thin film resistor performance into the field of low ohmic values for use in very accurate current sensing applications. Most thin film chips have a minimum value in the range of one to 10Ω, but TT Electronics’ LCS series uses a proprietary technology to extend this down to 100mΩ.The resistors also feature low sensitivity to temperatu ...
Riedon has today announced a cost-effective power resistor design achieving superior performance in high-frequency applications and high-speed pulse circuits. The various TO-style resistors within Riedon’s PF family are non-inductive and use an advanced power film formed on a heat-conducting alumina substrate that is metalized and soldered to a heat-dissipating copper plate tab.This process offers devices featuring excellent thermal resistance in small-size, thin-profile TO-style packages for hi ...
