Current is the intensity of electron flow in a conductor.

Current is the intensity of electron flow in a conductor.

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

Answer: (A)

Electric current is the measure of how much electric charge passes a point in a circuit each second. In a metal conductor, the charge carriers are electrons, so the amount of their flow per unit time—their rate of passage through a cross-section—defines the current. This is why current is described as the intensity or magnitude of electron flow, and it is measured in amperes (coulombs per second). Voltage, on the other hand, is the potential difference that pushes charges to move; it’s the driving force, not the amount of flow by itself. Power is the rate at which energy is transferred, related to current and voltage by P = VI or P = I^2R. Resistance is the property that opposes current, determining how much current flows for a given voltage via I = V/R. So the statement correctly identifies current as the intensity of electron flow in a conductor.
