Static electricity occurs when electrical charges build up on the surface of an object. This usually happens through —when two different materials rub against each other, electrons are transferred from one to the other. One object becomes positively charged (losing electrons), while the other becomes negatively charged (gaining electrons).
Dynamic electricity is what powers our homes and devices. It is measured in terms of: The electrical pressure or "push." Current (I): The rate of flow of the electrons. Resistance (R): The opposition to that flow. Key Differences Static Electricity Dynamic Electricity Movement Charges are stationary on a surface. Charges flow continuously in a conductor. Duration Short-lived (discharges quickly). Continuous (as long as the circuit is closed). Utility Limited (photocopiers, air filters). Essential (powering appliances, electronics).

Because these charges are "static," they do not flow. Instead, they remain on the surface until they find a way to equilibrate. This often results in a , such as the spark you feel after walking across a carpet and touching a metal doorknob, or the massive discharge of lightning during a storm.
