Hello.
I have a small AA battery powered desktop vacuum cleaner.
It uses 2 double A batteries
When the vacuum is not running and I check the battery voltage (combined) I get 2.95v
But once I turn ON the vacuum, the voltage surges to 7v or more.
I even measure MUCH higher voltage at the motor terminals.
I don't understand this.
However, I'm guessing it has to do with OHMs Law and the change in current?
Thanks
