Correct Answer:
B. Amperes
Electric current, which is the flow of electric charge, is measured in Amperes (A). The Ampere is the SI (International System of Units) base unit of electric current, named after French physicist André-Marie Ampère. One ampere is defined as one coulomb of charge passing through a point in one second. Understanding this unit is fundamental to electrical engineering and physics.
- Volts (V) are the SI unit of electric potential difference, or voltage, which is the force that drives the current.
- Candela (cd) is the SI base unit of luminous intensity, used to measure the power emitted by a light source in a particular direction.
- Watts (W) are the SI unit of power, representing the rate at which energy is transferred or converted.
