What is a Voltage Sensor?

A sensor is an electrical device that detects and responds to a certain sort of signal, such as optical or electrical. The use of sensor methods in voltage (or) current measurement has become an excellent alternative for voltage and current measurement methods. Sensors provide many benefits over tra

Uninterruptible Power Supply (UPS): Block Diagram & Explanation

What is a UPS (Uninterruptible Power Supply)? An Uninterruptible Power Supply (UPS) is defined as a piece of electrical equipment which can be used as an immediate power source to the connected load when there is a failure in the main input power source. In a UPS, the energy is generally stored in f

What is Bridge Rectifier? Explain it’s Working Principle

AC (Alternating Current) is transformed into DC (Direct Current) using the rectifier circuit. Half-wave rectifiers, Full-wave rectifiers, and Bridge rectifiers are the three basic kinds of rectifiers. All of these rectifiers have the same primary purpose, which is to convert current, however they do

Voltage Divider: What is it?

What is a Voltage Divider? A voltage divider is a fundamental circuit in the field of electronics which can produce a portion of its input voltage as an output. It is formed using two resistors (or any passive components ) and a voltage source . The resistors are connected in series here and the vol

Voltage to Current Converters (V to I Converters)

What is a Voltage to Current Converter (V to I Converter)? A voltage to current converter (also known as a V to I converter) is an electronic circuit that takes current as the input and produces voltage as the output. But why would we do this? Well for instrumentation cicuits when creating an analog

Voltage in Series Circuits

What are Voltages in Series? A series circuit or series connection refers to when two or more electrical components are linked together in a chain-like an arrangement within a circuit. In this kind of circuit, there is only a single way for charge to pass through the circuit. The potential variation

Voltage Follower OP Amplifier: What is it?

What is a Voltage Follower? A voltage follower (also known as a buffer amplifier, unity-gain amplifier, or isolation amplifier) is an op-amp circuit whose output voltage is equal to the input voltage (it “follows” the input voltage). Hence a voltage follower op-amp does not amplify the input signal

Voltage Source: What is it

What is a Voltage Source? A voltage source is defined as a device that delivers electric power to a connected circuit. In simpler terms, it’s like a push force that keeps the electrons moving continuously through the wire it’s connected to. Think of it as a pump in a water system, only this pump is

Voltage Regulators: Linear, Shunt, and Zener Diode

What is Voltage Regulation A voltage regulator is an electronic or electrical device that can sustain the voltage of power supply within suitable limits. The electrical equipment connected to the voltage source should bear the value of the voltage. The source voltage should be in a certain range whi

Voltage Multiplier

It is in actuality a modified capacitor filter circuit (rectifier circuit) which makes a DC output voltage that is two or more than two times the AC peak input. In this section, we can look into full-wave voltage doubler, half-wave voltage doubler, voltage tripler and finally quadrupler . Half Wave

Regulated Power Supply: Circuit Diagram & Types

What is a Regulated Power Supply? A regulated power supply converts unregulated AC ( Alternating Current ) to a constant DC (Direct Current ). A regulated power supply is used to ensure that the output remains constant even if the input changes. A regulated DC power supply is also known as a linear

Direct Current: What is it?

What is DC Current? DC stands for Direct Current, although it is often called “DC Current”. DC current is defined as a unidirectional flow of electric charge . In DC current, the electrons move from an area of negative charge to an area of positive charge without changing direction. This is unlike a
