Hi there!
My knowledge of electronics is pretty vague to say the least and i need some basic help.
Firstly I want to know if i connect a device which requires 12V at 320mA to an 18 V battery, will the device eventually burn out??
Following that, will adjusting the voltage just cause the device (cpu fan) to speed up and slow down?
Im having difficulty getting my head around the relationship between voltage and current. Ive looked at books, but they loose me when they go off at tangents!!
My last question is if i connect this fan to a transformer with an output of 9v at 1amp, will the fan burn out? and if so how do i calculate what resistor i need to drop the current??
Would appreciate it a lot of anyone could help me out as i really do need it
Thanks again!
