Hello,
I have few questions about batteries and AC->DC adapters
1- in AC-DC converter:
if I have a device required 12v and 1amp .. will it hurt the circuit if I connect 12v but more amps ? I heard it draw only required currents .. is that true ?
2- in batteries:
why when we buy batteries .. some of them last more than other .. some of them make the device runs faster (e.g. razor, rc car ... ) you really feel that it runs faster.
Q:
-what does make devices runs faster/stronger .. battery with high voltage, amp or discharge rate (C)?
- what makes battery last longer ? higher V or higher Amp ?
- when battery is being used .. what is decreasing in it .. is it V or A ?
thanks
