Although there are several ways to sense current flowing from a source such as a battery, or to a load such as a motor, the current-sense resistor is among the most widely used approaches. There are ...

LED output is a function of the current through it. So to drive the device, it would seem simple enough to set the LED current with a series power resistor. But there’s a problem with this idea. First ...

In test-and-measurement applications, you must provide overvoltage protection for the output terminals of amplifiers, power supplies, and similar components. The conventional way to accomplish this ...

Linear Technology’s LTC4213 electronic circuit breaker senses load currents using the RDS(ON) of an external MOSFET. This new method not only reduces voltage and power loss in the switch path, but ...

The hostile environments found in many of today’s applications require integrated circuits to withstand high voltage and current. Systems designers need to select high-performance ICs to use in these ...

Infineon Technologies is to develop a two-terminal semiconductor device that acts as a circuit breaker for hundreds of volts and amps: doubling the performance of its mains-voltage super-junction ...

The recommended maximum total voltage drop on branch-circuit conductors is ____%. Article 210 outlines the requirements for branch circuits. Branch-circuit rating rules are covered in Part II of this ...

When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. When resistors are connected in series ...

Vishay Intertechnology, Inc. (NYSE: VSH) introduced a new AEC-Q200 qualified, high-power thick film resistor engineered to ...

The two resistors may have fixed values or one may be an LDR, a thermistor or other input device. The supply voltage is divided in the ratio of the resistances in the voltage divider. For the voltage ...
