How is electric current measured?

Electric current is measured in amperes, often shortened to "amps." This unit quantifies the flow of electric charge in a circuit. Specifically, one ampere is defined as one coulomb of charge passing through a given point in one second. Amperes provide a clear understanding of how much electricity is flowing and are crucial for determining the capacity and safety of electrical systems.

The other units mentioned relate to different aspects of electricity. Watt measures power, which is the rate at which energy is consumed or produced. Volt measures electric potential difference, which can be thought of as the pressure that pushes electric charges through a circuit. Ohm measures resistance, which indicates how much a material opposes the flow of electric current. Understanding current in terms of amperes allows for practical applications in electrical engineering and everyday use of electronic devices.
