Electrical units are measurements used to quantify various aspects of electricity. The most common units include volts, which measure electrical potential; amperes (or amps), which measure the flow of electric current; and ohms, which measure electrical resistance. These units help in understanding how electrical systems operate and are essential for designing and troubleshooting electrical circuits. Another important unit is the watt, which measures electrical power and is calculated by multiplying volts by amps. Additionally, kilowatt-hours (kWh) are used to measure energy consumption over time, commonly seen on electricity bills. Understanding these units is crucial for anyone working with or studying electricity.
