Hi readers,
Hairdryers (240V AC) actually works on a design which current passes through the heating filament (Maybe consume 220V) to produce a lot of heat whereas through the DC motor (Maybe consume 20V).
I have always been curious about this
Question: Hair dryer has an option of choosing the speed of motor (more air flow) and heat produced by adjusting the knob. When the hairdryer is operating at cool mode (only motor) and no heating filament, this would mean that the motor would consume 240V which is extremely dangerous. So, how does this hairdryer circuit for just actually operating the fan without the heating filament. I have opened a hairdryer actually and found no AC to DC adapter which help to regulate 20V max to DC motor. Any suggestions, lads ? Thank you
