What is the rate of electric charge flow?

• A. Voltage
• B. Resistance
• C. Charge
• D. Current

Answer: (D)

Understanding current means recognizing it as the rate at which electric charges move past a point. It’s the flow rate of charge, like how many gallons pass a point per second in a pipe. By definition, current equals the amount of charge transferred divided by the time it takes (I = ΔQ/Δt). That’s why current is measured in amperes (coulombs per second). Voltage is the push that motivates charges to move, while resistance is what opposes that flow. Charge is the total amount of electricity present, not how fast it moves. So the rate of electric charge flow is current.
