Hello
Can someone please explain to why when using a higher voltage for a motor you draw less current. I was trying to think about this, and using ohms law V=IR I cannot see this. Since the current is equal to V/R it would appear from this that if the voltage increased, then the current would increase assuming that the resistance was fixed. Is that my problem, is the resistance not fixed? Sould I be using some other equation instead of V=IR to model this relationship? Are there inductive properties to take into account?
I would appreciate any explanations or point me to any references where I could find information on this subject. A scientific explanation would be great if anyone knows.
Thanks
