di ba same current consumption whether 1, 2 0r 3 ang setting ng fan? may mga resistors of different resistor values say, no resistor (coils) for full (no.3) fan setting, then may ex. 1kohm for no. 2 and 2 kohms for no. 3. kaya basically you're just loading up the battery going to the fan para mabago mo yun speed.
