Voltage (V): Voltage is a measure of electrical potential difference between two points in a circuit. It is often compared to the pressure in a water pipe. The unit of voltage is the volt (V), named after Alessandro Volta, another notable physicist in the field of electricity. Voltage provides the driving force that pushes electric charge (electrons) through a circuit. In practical terms, voltage represents the energy per unit charge available to move electrons in the circuit. A higher voltage implies more energy and a greater potential for current flow.Also Check - Work, Energy & Power Formula
Current (I): Current refers to the flow of electric charge within a circuit. It is measured in amperes (A), which is named after André-Marie Ampère, a pioneer in the study of electromagnetism. Current is the rate at which charge flows through a conductor and is often compared to the flow rate of water in a pipe. In an electrical circuit, electrons move from a region of higher voltage (positive terminal) to a region of lower voltage (negative terminal), creating a current flow. The direction of current flow is conventionally considered from positive to negative, even though electrons actually move in the opposite direction.Also Check - Unit, Dimension & Vector Formula
Resistance (R): Resistance is a property of materials that opposes the flow of electric current. It is measured in ohms (Ω), named after Georg Simon Ohm himself. Resistance can be thought of as the restriction or hindrance encountered by electrons as they move through a conductor. Materials with high resistance impede the flow of current, while materials with low resistance allow for easier current flow. Resistance is influenced by various factors, including the material's composition, temperature, and physical dimensions. It plays a crucial role in determining the behavior of electrical circuits.Also Check - Heat Transfer Formula
