What is a Non-contact AC voltage detector? It is an AC voltage detector, that can be used to test live wires without any connection, hence the name. Therefore, it is safer than the neon screwdriver ...

Sometimes, we might need an AC bulb flasher circuit that can blink a series of bulbs in a particular time interval for decorative purposes. By controlling the flashing time interval and sequence, we ...

Most of the power supply these days are very reliable due to advancement in technology and better design preferences, but there is always a chance of failure due to a manufacturing defect or it can be ...

Check out this interesting wideband AC millivoltmeter circuit from 1990. The simple design features 12 ranges, decent accuracy, 200 µV accuracy, and a frequency range from 20 Hz to more than 2 MHz.

If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...
