low current voltage damage

There isn't any risk of damage from supplying power which is too low in current or voltage right?

Hi,

There isn't any risk of damage from supplying power which is too low in current or voltage right?

Why what have you done.lol

If you have connected up a 12V device with 9V then probably no problem, but circumstances can dictate if this is true for higher voltages.
So please elucidate. (Did you let the smoke out?)

Tom.. :slight_smile:

There most certainly is a risk of damage. If the voltage is too low to saturate a MOSFET it could overheat. If the current is too low to saturate a BJT it could overheat. If the voltage / current is too low someone like me could get frustrated the device is not working and smash it with a hammer.

Not very high, I'm planning to power a gsm shield/uno thru usb before using a power supply. should be alright?

You will then most certainly let all the smoke out. :slight_smile:

There is a risk that you will damage the thing that is supplying the power, if you connect something that draws more current than it can provide.
