WebYou would be creating a short circuit if you just connect an LED without a series resistor. It also depends on your LED's forward voltage (Vf) which is a characteristic of the LED. If the LED's Vf over 3V, it won't turn on and nothing will happen. If it's under 3V and there's not a resistor, lots of current will go through, likely burning it.
