Tolerance
Tolerance in electronic components refers to the allowable deviation from the specified value. It indicates the range within which the actual value of the component can vary while still meeting the manufacturer's specifications. Tolerance is typically expressed as a percentage of the nominal value, such as ±5% or ±10%. A lower tolerance indicates a tighter range of acceptable values, resulting in more precise and consistent performance.

Resistance
Resistance is a measure of the opposition to the flow of electric current in a conductor. It is measured in ohms (Ω). The higher the resistance, the more difficult it is for current to flow. Resistance is caused by the collisions of electrons with atoms and molecules in the conductor. The more collisions that occur, the higher the resistance.
