How to Calculate Equivalent Resistance

What is Equivalent Resistance? The equivalent resistance is defined as a point where the total resistance is measured in a parallel or series circuit (in either the whole circuit or in a part of the circuit). The equivalent resistance is defined between two terminals or nodes of the network. Equival

Electrical Resistance: What is it?

What is Electrical Resistance? Resistance (also known as ohmic resistance or electrical resistance) is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). The larger resistance, the greater the barrier agains

Nature of Electricity and Concept of Electricity

Electricity is the most common form of energy. Electricity is used for various applications such as lighting, transportation, cooking, communication, production of various goods in factories and much more. None of us exactly know that what is electricity . The concept of electricity and theories beh

What is Electric Power?

Voltage and current are two basic parameters of an electric circuit . But, only voltage and current are not sufficient to express the behaviour an electric circuit element . We essentially need to know, how much electric power , a circuit element can handle. All of us have seen that a 60 watts elect

What is the Si System of Units?

Units are defined as those tools using which we can measure any physical quantities effectively. For example, if we want to measure length then that can be measured in meters, centimeters, feet etc, again if we have to measure mass then that can be measured in kilograms, grams etc. So from the above

What is Drift Velocity?

Drift velocity is defined as the net velocity of a particle that undergoes random changes in direction and speed. This concept is typically associated with free electrons moving within a conductor . Imagine these free electrons traversing the conductor with arbitrary speeds and in random directions.

What is Power in AC Circuit?

AC circuits are usually three-phase for electrical distribution and electrical transmission purposes. Single phase circuits are commonly used in our domestic supply system. The total power of a three-phase AC circuit is equal to three times the single phase power. So if the power in a single phase o

What is Electric potential?

Similarly, the potential difference between two points is defined as the work required to be done for bringing a unit positive charge from one point to other point. When a body is charged, it can attract an oppositely charged body and can repulse a similar charged body. That means, the charged body

What is Electric Charge?

What is Electric Charge? Every matter in this universe is made of atoms . The atoms are electrically neutral. This is because, each atom has equal number of protons and electrons. Protons have positive charge. In an atom, protons sit in the central nucleus along with electrically neutral neutrons. T

What is Root Mean Square Value of AC Signal?

These are the questions which come in our minds every time when we are dealing with AC circuits. Suppose, we have a simple DC circuit (figure – 1) and we want to replicate it in an AC circuit. We got every thing same, except supply voltage which is now to be an AC supply voltage . Now, the question

Superposition Theorem

The superposition theorem is a fundamental principle in electrical engineering that states that the response of a linear system to any input can be represented as the sum of the responses to individual inputs. In other words, the output of a linear system to a combination of inputs is equal to the s
