In hydraulics, current is equivalent to what?

• A. Pressure
• B. Flow rate
• C. Temperature
• D. Viscosity

Answer: (B)

In a hydraulic system, current is the rate at which fluid moves through the system, i.e., the flow rate. It’s the amount of fluid passing a point per unit time, just as electrical current is the charge flow per unit time. The flow rate is driven by the pressure difference and is affected by the system’s resistance to flow, so increasing pressure or reducing resistance raises the flow rate. Units like cubic meters per second or gallons per minute express this flow. Temperature and viscosity influence how easily the fluid can flow, and thus can change the flow rate, but the quantity that current corresponds to is the flow rate itself. Pressure is the driving force (like voltage), not the current; viscosity modifies flow behavior, not the fundamental meaning of current.
