Resistance formula: Electrical resistance is a

Electrical resistance is a quantity that measures the opposition offered by a device or a material to the flow of current through it. The S.I unit of resistance is ohms (Ω). A resistor is an electric component that is used to offer the desired resistance in a circuit. In this article, we shall be discussing the various electrical resistance formula used to find the resistance offered by a conductor to the flow of current. Formula For Electrical Resistance When we know the length and the ... R = V I is the resistance formula . Resistance is the measure of any object's opposition to the flow of electric current. A resistor is an electrical component that provides a defined amount of resistance in a circuit. Resistance is the property of materials that permits electric current to flow. Resistance obviously opposes the flow of a stream. Learn how to calculate electrical resistance using Ohm's law and resistivity. Find out the factors that affect resistance and resistivity, and the difference between them.
