Current electricity is defined as the flow of electric charge per second, measured in what unit?

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

Answer: (B)

Electric current is the rate at which electric charge flows through a point in a circuit. Since it’s charge per unit time, its unit is the ampere, defined as one coulomb per second (symbol A). Volts measure potential difference, ohms measure resistance, and watts measure power, so they describe other electrical quantities, not the rate of charge flow.
