What is DC Voltage? DC voltage stands for “Direct Current Voltage”. While this sounds confusing, the term “DC” has become used more broadly to refer to a system that has constant polarity. Hence DC voltage is a voltage that produces or would produce a DC current . Conversely, an AC voltage is a volt

What is Open Circuit Voltage? When an open circuit condition is created in any device or circuit, the difference of electric potential between the two terminals is known as the open-circuit voltage. In network analysis, the open-circuit voltage is also known as the Thevenin Voltage . The open-circui

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

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

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

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

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

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

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

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

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

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
