Current is measured in which unit?

• A. Volts
• B. Ohms
• C. Amperes
• D. Watts

Answer: (C)

Current is measured in amperes, which are often referred to as "amps." One ampere is defined as the flow of one coulomb of charge per second. This unit is part of the International System of Units (SI) and is fundamental in the study of electricity and electronic currents. Understanding current is crucial for various applications in building maintenance, particularly when working with electrical systems. Amperes help in determining how much electrical charge flows in a circuit, which is essential for ensuring that electrical systems are properly designed and maintained. This measurement informs decisions about wire sizing, circuit breaker ratings, and overall electrical safety in buildings. Other options reflect different electrical properties: volts measure electrical potential (or voltage), ohms measure resistance in a circuit, and watts measure power, which is a product of voltage and current. Each of these units serves a distinct purpose but does not directly measure current like amperes do.
