What is the basic unit of electric charge?

• A. Ohm
• B. Voltage
• C. Amperage
• D. Coulomb

Answer: (D)

The basic unit of electric charge is the Coulomb. This unit is defined within the International System of Units (SI) and is symbolized as 'C'. One Coulomb is quantitatively defined as the amount of charge that is transferred by a constant current of one ampere in one second. This relationship highlights how charge is interrelated with current and time, which are fundamental components of electrical circuits. Understanding the Coulomb is crucial for anyone studying electronics, as it serves as a foundational concept for further study in electric fields, capacitance, and the behavior of electrons. While Ohm, Voltage, and Amperage are essential electrical concepts, they refer to resistance, electrical potential difference, and current flow, respectively, rather than directly addressing the concept of charge itself.
