In Python Physics Lesson #35, we explore how to simulate LRC circuits and understand their behavior over time. This video breaks down the concepts of inductance, resistance, and capacitance, and shows ...

As analog-to-digital and digital-to-analog converter resolutions increase and power supply voltages decrease, the size of a least significant bit becomes smaller. This makes signal-conditioning tasks ...

Switching ac power on and off has been a challenge since Edison and others started switching power more than 125 years ago. Now, a solid-state relay (SSR) uses a patented zero-voltage crossing ...

Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...

The rules of the National Electrical Code are written for people who have a pre-existing knowledge of electricity. In order to make sense of the Code, you must first understand basic electrical ...

For an undamped LC circuit excited by an AC voltage source through simple phaser equations, we come to see that the circuit becomes short circuited at the resonant frequency. However if we analyze the ...
