Toggle parts to complete the loop. Can you light the LED without burning it out?

  1. 1Check the partsKeep the battery and resistor switched on.
  2. 2Close the switchTurn on Switch closed to complete the loop.
  3. 3Watch the LEDLook for the glow and read the current message.
  4. 4Experiment safelyChange the voltage. If the LED pops, add the resistor and replace it.
5V

The switch is open, so the loop is broken. Close it!

Battery voltage: 5V

Did you know?

Ohm's law: Current = (Voltage โˆ’ LED voltage) รท Resistance. That's how engineers pick the right resistor!
