This circuit is a Mosfet-based linear voltage regulator with a voltage drop of as low as 60mV at 1A. The circuit uses a 15V-0-15V transformer and employs an IRF540 N-channel Mosfet (Q1) to deliver the ...

System Sensor offers a Web-based Voltage Drop Calculator that allows users to quickly and easily lay out audible/visible notification device circuits using the company’s notification appliances. The ...

Environmental systems that precipitate dust and carbon particles frequently use high-voltage dc power supplies. However, failure of high-voltage components caused by a change in their properties over ...

Using a low-value resistor to sense current is a direct application of Ohm’s Law, yet requires understanding of the key parameters and tradeoffs. Although there are several ways to sense current ...

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 ...

Electrical equipment that operates below its voltage rating can overheat or power down. Here's how to determine your load's operating voltage. Voltage drop across switchgear and feeder and branch ...

Pickering Interfaces, a supplier of modular signal switching and simulation solutions for use in electronic test and verification, has announced a new family of high voltage programmable resistor ...

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 ...

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 ...

Q: The left taillight on my pickup is somewhat dimmer than the one on the right side. It’s not bad enough to go through the trouble and expense of having fixed it. But it bugs me. Any chance you have ...
