What is Regulated Power Supply? – Circuit Diagram, Operation, and Applications

Updated on 19-Dec-2022 13:54:13
We have several electrical and electronic circuits that require a DC power supply to operate. But, due to some technical and economical limitations, we cannot use conventional sources of DC power such as batteries and DC generators. In this situation, we use an electronic circuit that can convert AC power into DC power, such a circuit is known as rectifier. However, the DC power output of a rectifier is a fluctuating DC voltage and current which may damage the electronic circuit. Thus, to overcome the problem of variation in voltage, some voltage regulating devices are used so that we can ... Read More

What is Direct Current? – Definition, History, Measurement, and Applications

Updated on 19-Dec-2022 13:49:52
In electrical and electronics, the term electric current (or current) is used to represent the flow of electric charge (electrons or holes) in a particular direction. Hence, the electric current is simply defined as the directed flow of electrons (in metals), and electrons and holes (in semiconductors). In actual practice, the electric current can only flow through metals and semiconductors, while insulators block the flow of electric current through them. Based on the direction of flow, the electrical current is broadly classified into two types namely direct current (DC) and alternating current (AC). In this article, we will discuss the ...

What is a Sinusoidal Wave Signal – Definition and Importance

Updated on 19-Dec-2022 13:43:58
A sinusoidal wave signal is a type of periodic signal that oscillates (moves up and down), periodically. The geometrical waveform of a sinusoidal signal forms an S-shape wave in one complete cycle. A sinusoidal can be a sine functioned signal or cosine functioned signal. Thus, a sinusoidal signal can be defined as, $$\mathrm{y=sin\, x}$$ $$\mathrm{y=cos\, x}$$ Both sine and cosine signals are the types of sinusoidal wave signals. But, the cosine signal is advanced with respect to the sine signal by 90° in time. The sinusoidal wave signal has a smooth wave that oscillates above and below zero and used ... Read More

What is a Bleeder Resistor? – Definition, Formula, and Applications

Updated on 19-Dec-2022 13:42:18
What is a Bleeder Resistor? In electronic circuits, a resistor which is connected in parallel with the output of a high voltage power supply for discharging the filter capacitors of the power supply when the circuit is turned off is referred to as a bleeder resistor. It is also known as a leakage resistor or capacitor discharge resistor or safety discharge resistor. The bleeder resistor is primarily used for safety reasons because it eliminates the possibility of a left over charge that may cause an electric shock. Generally, a bleeder resistor is a standard resistor instead of a specialized ... Read More
