What are Active and Passive Circuit Elements (Components)?Active and passive components form the two main types of electronic circuit elements. Anactive componentsupplies energy to anelectric circuit, and hence has the ability to electrically control the flow of charge. Apassive componentcan only receive energy, which it can either dissipate or absorb.Types of Electronic ComponentsElectronic elements that make up a circuit are connected together by conductors to form a complete circuit. If these

What is ELI the ICE man?ELI the ICE man is used to remember the relationship between current and voltage in an inductor and capacitor. ELI the ICE man stands for the fact that voltage [E] leads current [I] in an inductor [L] (that’s the ELI part) and current [I] leads voltage [E] in a capacitor [C] (that’s the ICE part).ELI the ICE man is a mnemonic. That is to say that it’s a learning technique that aids information retention in human memory.So ELI the ICE man helps us remember that: ELI: Volta

What is a Schmitt Trigger?A Schmitt Trigger is a comparator circuit with hysteresis implemented by applying positive feedback to the noninverting input of a comparator or differential amplifier. A Schmitt Trigger uses two input different threshold voltage level to avoid noise in the input signal. The action from this dual-threshold is known as hysteresis.The Schmitt Trigger was invented by American scientist Otto H Schmitt in 1934.The normal comparator contains only one threshold signal. And it

What is an Open Circuit?An open circuit is defined as an electric circuit in which current does not flow. Current can only flow in a circuit if it finds a continuous path—known as a “closed circuit”. If there’s a break anywhere in the circuit, you have an open circuit, and current can not flow.In an open circuit, the two terminals are disconnected. Hence the continuity of the circuit is broken. But while current cannot flow through the circuit, there is some voltage drop between two points of a

A planar circuit is a circuit that can be drawn on a flat surface without any wires crossing each other. A non-planar circuit is a circuit that cannot be drawn on a flat surface without any wires crossing each other. Planar and non-planar circuits have different properties and methods of analysis. In this article, we will explain what planar and non-planar circuits are, how to analyze them using graph theory and loop current method, and what are some applications of these circuits in electrical

There are two types of system available in electric circuit, single phase and three phase system. In single phase circuit, there will be only one phase, i.e the current will flow through only one wire and there will be one return path called neutral line to complete the circuit. So in single phase minimum amount of power can be transported. Here the generating station and load station will also be single phase. This is an old system using from previous time.In 1882, new invention has been done o

Before studying electrical engineering it is essential to know that angular relation between mainly voltage and current in a system. For understanding the relation between voltage and we should first know definition of vector and go through vector algebra and vector diagram.Definition of VectorThere are some quantities which have both magnitude and as well as their direction of action. This type of quantities is called vector quantity. This is how one can make basic definition of vector in very

In several electrical and power applications, the measurement of current flow is essential.Hence, current measurement is commonly required for monitoring and controlling applications.Depending on the kind of application, many types of current sensors with specialised current sensing technologies are available to detect (or)measure current flow.A current sensing resistor, also known as a shunt resistor, is the most prevalent methodto measure current flow in any application.This postdescribes shun

To derive the relations between line and phase currents and voltages of a star connected system, we have first to draw a balanced star connected system.Suppose due to load impedance the current lags the applied voltage in each phase of the system by an angle ϕ. As we have considered that the system is perfectly balanced, the magnitude of current and voltage of each phase is the same. Let us say, the magnitude of the voltage across the red phase i.e. magnitude of the voltage between neutral point

What is a Diode?Diodes are two-terminal electrical devices that act as a one-way switch, allowing current to flow (transfer) only in one direction. These diodes are made from semiconductor materials such as Silicon, Germanium, and Gallium arsenide.The diode’s two terminals are referred to as the Anode and Cathode. The functioning of a diode may be categorised into two types based on the potential difference (potential energy)between these two terminals: If the anode has a greater voltage than th
