Hello,
What do you call to the switch of the electric fan which often numbered 1, 2, 3, 4. 1 is the slowest and 4 is the fastest. Okay, not to mention the number zero which means off.
So, what do you call to that switch? Also how this switch works? How this switch fast and slow the electric fan?
Okay, how can I figure out the internal resistance of a battery?
Please, I need your help.
Any help would be appreciated.
Thank you so much.
