Fluids and circuits
Pressure, buoyancy, flow, basic circuits, and instrumentation.
Fluids and circuits are both flow systems. In fluids, pressure gradients drive volume flow. In circuits, voltage drives current. The MCAT tests whether you can compare systems when resistance changes or when geometry changes.
- Pressure gradients drive fluid flow
- Flow depends strongly on radius
- Parallel circuits reduce total resistance
- Series circuits increase total resistance
- Fluid flow and current flow follow similar logic
Write a two-sentence comparison between fluid flow and electrical current. How does resistance affect each?
