  • the magic smoke came out of the resistor and I can still smell it... the fact that there is still a voltage through the bulb confuses me
  • 4V is across the resistor, the current is 400mA, the resistance of the bulb is 20 ohms and if you don't have something around a 2W resistor, it glowed a bit too right before you smoked it!
