Current Electricity

Ohm’s law is key to understanding how resistance works. The relationship between the current flowing in a circuit and the potential difference across its terminals was found by Georg Simon Ohm In 1827. He stated that when the temperature remains constant, the current in a circuit is directly proportional to the potential difference across the […]

Reactance (X) is defined as the opposition present in alternating current by either inductance or capacitance in electrical circuits. The phrase ‘reactance’ was coined by a French architect named M. Hospitalier in the year 1893. Sometimes, reactance and resistance are confused with one another but they are not the same. The difference between reactance and

Reducing the complexity of a circuit by merging related parts with series or parallel connections is one of the simplest and most beneficial things. Resistors, voltage sources, and current sources can all be combined and replaced with equivalents in the right circumstances. Let’s begin with resistors. In many cases, complicated resistor networks may be reduced

If the two conditions (series and parallel) in an electronic circuit are satisfied and the circuit is functioning correctly, then the charge flows through the circuit. The idea is that there is a flow of electrons or an electric charge flow. In this sense, the term “current” merely means that something is happening within the

Wattless current is also known as idle currents. The current which is involved in an alternating circuit(AC) is known as wattless currents, as the average power consumed in such a type of circuit corresponds to zero. In other words, the current which flows through such an electric circuit in which the power consumption is zero

Any movement of electric charge carriers, such as subatomic charged particles (e.g., electrons with negative charge, protons with positive charge), ions (atoms that have lost or acquired one or more electrons), or holes, is referred to as electric current (electron deficiencies that may be thought of as positive particles). The quantity of charge passing any

The German physicist – Georg Simon Ohm was the first person to study the relationship between resistance, current and voltage. He answered the question ‘what is resistance’, stating that resistance is the measure of opposition to the flow of electric current in a circuit. The S.I. unit of resistance is known as Ohms, after its

Power in AC circuits is defined as the amount of energy delivered per unit of time by the circuit. It is used to calculate how much total power is required to run a load. In an AC circuit, the power factor is defined as the ratio of real power (P) and apparent power (S). The

In this article, we are going to talk about the idea of impedance and its properties. This is a very crucial subject topic in electronics, and its concept and mechanism come from the analysis of AC (Alternating Current). We limit our study to inputs to electric circuits that look like a sinusoid, sine, or cosine
