1-Can a simple variable resistor be used instead of the fan speed regulator? And why? 2-Mention some applications in which such regulators can be used? 3-Can these organizations use to regulate the speed of cooling engines or heating devices? And why? 4-Mention some of the holidays you saw due to the fan speed regulator in your working life? Do you suggest a method to avoid or fix it?
