WebJan 8, 2024 · DC voltage motor control also provides a limited range of speed control—and limited efficiency--because of the need for a specific start-up voltage that causes the fan to begin turning. The limited range of speed control occurs because of the minimal difference between the start-up and operating speed voltages. WebIf you connect a source of electricity with a fixed voltage (constant voltage supply) to a capacitor through a resistor, the capacitor will charge, the current that flows will be initially large but will decrease over time. The formula describes that. simulate this circuit – Schematic created using CircuitLab I = V R e − t / R C
