Question
What component is traditionally used to regulate the
speed of a ceiling fan?Solution
A resistor serves as the conventional component for regulating fan speed. By adjusting the resistance, the voltage across the fan alters, thereby controlling its speed. Higher resistance leads to a lower fan speed due to the increased voltage drop.
