Electrical energy is the capacity to perform work, derived from the flow of electric charge. It's commonly measured in kilowatt-hours (kWh), representing the consumption of 1,000 watts for one hour. Other fundamental units include volts (potential difference), amperes (current flow), and watts (power). Understanding these units is crucial for assessing electrical system performance and consumption.

Electrical distributors are businesses that supply electrical products to contractors, businesses, and sometimes directly to consumers. Major types include wholesale distributors who serve the professional trade, and retail outlets that offer a range of electrical supplies for DIY projects. They stock everything from wire and conduit to circuit breakers and lighting fixtures, ensuring availability for various electrical installations and repairs.

The standard unit for measuring electrical current is the ampere, commonly called an amp. It quantifies the rate at which electric charge flows through a conductor. For example, a household appliance might draw a certain number of amps, which dictates the required circuit breaker size and wire gauge to ensure safe operation and prevent overheating.
