  • Resistance

    Resistance is a fundamental property of electronic components that measures their opposition to the flow of electric current. It is denoted by the symbol "R" and is measured in ohms (Ω). Resistance is caused by the collisions of electrons with atoms in a material, which generates heat and reduces the flow of current. Components with higher resistance will impede the flow of current more than those with lower resistance. Resistance plays a crucial role in determining the behavior and functionality of electronic circuits, such as limiting current flow, voltage division, and controlling power dissipation.
