Generally a DC signal is used to control circuit which is driven by high voltage like controlling AC home appliances with DC signals from microcontrollers. So as of now we understand what is a relay ...

Here this simple preamp circuit is used for amplifying the AUX output of Mobile phone and amplifying the voice input given by the condensor mic or microphone. ... Circuit Diagram and Explanation: ...

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.

Simple Circuit Diagram is a collection of completely free electronic circuit schematic diagrams. For each diagram, they explain the use of the circuit as well as provide in-depth explanations of all ...

To design a circuit diagram for a simple calculator, you need to decide on the input and output formats, the number of bits and the functions you want to include.

A tool to simulate simple AC circuits. The project objective is to develop a CAD (Computer Aided Design) tool to simulate simple AC circuits that contains only (independent voltage sources, ...

Impedance is crucial in AC circuit analysis because it enables engineers and technicians to calculate how AC voltage and current behave within a circuit. ... Through simple explanations, practical ...

Like most other simple circuits, this circuit also has a disadvantage: It is incompatible with some load-power and ac-mains-voltage values. When a fuse burns out, the load stays connected to the ac ...

Figure 9. 6.6 W, single output (3.3 V) Flyback converter circuit diagram. Designing PDs to operate from AC-DC adapters. Keep PD DC-DC design simple: AC-DC operation is temporary Requests are often ...

Low-power circuits commonly use transformerless power supplies. However, the use of earth grounds in many of these circuits creates a serious problem that is often ignored. The very popular ...

For simple circuits, this can work, but for something complex (no pun intended), it gets hairy fast. By the way, this example showed to elements in series. However, you can add reactances in ...
