In electrical and electronic circuits, the difference between potentials of two points is referred to as voltage or potential difference. Sometime we come across a term "open circuit voltage" while analyzing electric circuits. The term open circuit voltage is very common when we use Thevenin’s Theorem to analyze the circuit. ...

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, ... Read More

In electrical and electronic circuits, the term voltagevoltage is used to denote the potential difference between two points. Based on the nature, the voltage can be of two types namely – AC Voltage and DC Voltage. In this article, we shall confine our attention to the DC Voltage only. Here, ... Read More

In electrical and electronic circuits, we have to provide necessary for the operation of the circuit. For this purpose, we used energy sources such as voltage sources and current sources. The energy sources are the active circuit elements, i.e. these elements can provide power or power gain in the circuit. ... Read More

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 ... Read More

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 ... Read More

In electrical and electronic circuits, there are two basic electrical quantities namely current and voltage. Sometimes, we need to convert these two quantities into one another. For this, electronic circuits are designed which are known as converters. Based on conversion, there are two types of converters namely Voltage to Current ... Read More

An electronic circuit consisting of diodes and capacitors and converts an AC electrical signal from a lower voltage value to a higher DC voltage value is referred to as a voltage multiplier. Voltage multipliers are used in several electronic appliances to generate a voltage signal of few volts to millions ... Read More

In an electric circuit, when two or more electric circuit components are joined together in such a way that there is only one path for the flow of electric current, such connection of circuit components is referred to as series circuits. Therefore, in a series circuit, the current through all ... Read More

An electronic circuit in which the output voltage follows the input voltage is known as a voltage follower. In other words, a voltage follower is an electronic circuit whose output voltage remains the same as the input voltage. We can design a voltage follower using an operational amplifier. A voltage ...
