Circuit Elements

Circuit Elements: Let us take a brief review of three basic Circuit Elements namely resistance, capacitance and inductance. Resistance It is the property of the material by which it opposes the flow of current through it. The resistance of element is denoted by the symbol ‘R’. Resistance is measured in ohms (Ω). The relation between […]

Unit of Resistance

Unit of Resistance: Unit of Resistance – When a current flows in a material, the free electrons move through the material and collide with other atoms. These collisions cause the electrons to lose some of their energy. This loss of energy per unit charge is the drop in potential across the material. The amount of […]
