What Is Resistivity?

Simple Definition: Resistivity is the inherent property of a material that determines its ability to resist [forcefully oppose or stop] the flow of electric current [the flow of electric charge].…

What Is Electric Potential?

Simple Definition: Electric potential is a way to measure how charged a specific point is within an electric field, which is like an invisible force field created by charged particles.…

What Is Electromagnetic Induction?

Simple Definition: Electromagnetic induction is the creation of an electric current in a conductor [a material that allows electricity to flow through it] due to a changing magnetic field. When…

What Is Polarity?

Simple Definition: Polarity refers to the property of having two opposite or contrasting aspects or conditions. It is the quality of something that can be divided into two parts that…

What Is A Joule?

what is volt meter?

Simple Definition: A volt meter is a device used to measure the electrical voltage [the amount of electrical force] in a circuit. It consists of a display screen [a monitor…

what is a watt hour?

Simple Definition: A watt hour is a unit of energy (the amount of power used over a period of time) that measures the amount of electricity consumed by a device…

What Is A Volt?

Simple Definition: A volt is a unit of measurement that represents the amount of electrical force or pressure [the push or pull that makes electric charges move] in a circuit.…

What Is Direct Current?

Simple Definition: Direct Current (DC) is a type of electric current that flows in one direction only [without changing its direction], in contrast to Alternating Current (AC) that periodically changes…

What Is Alternating Current?

Simple Definition: Alternating current (AC) is a type of electrical current that periodically changes direction [flows back and forth]. Unlike direct current (DC), which flows only in one direction, AC…

What Is A Watt?

Simple Definition: A watt is a unit of measurement [a standard way to measure something] used to quantify [measure the amount of] the rate at which electrical power is generated…

What Is Voltage?

Simple Definition: Voltage is the measure of electrical potential difference [the difference in electric charge] between two points in a circuit. It represents the force that pushes electric charges [particles…

What Is Ampere?

Simple Definition: An ampere is a unit used to measure the flow of electric current [the movement of electric charges through a conductor]. It is named after the French physicist…

What Is Electric Charge?

Simple Definition: Electric charge is a fundamental property of matter that causes it to attract [pull] or repel [push away] other objects that have electric charge. For example, when you…

What Is EMF?

Simple Definition: EMF stands for electromagnetic field [a type of invisible energy created by electrically charged objects]. It consists of electric and magnetic fields that surround these objects. EMF has…
