Physicus Hints

What do I do with this High Voltage box?

  • 1 of 8: Open it (pull the lever at right) and turn it on.  Read about Electricity on your laptop.
  • 2 of 8: That thing at the top is a resistor.  One is missing.
  • 3 of 8: Put the second resistor in the empty slot.
  • 4 of 8: It says 760 volts.  To use the equation R = V/I (Resistance = Volts divided by Amps), we need amps, too.
  • 5 of 8: Did you see the note on the side of the house by the cellar?
  • 6 of 8: It said 4 amps.  So we have R = 760/4 = 190.
  • 7 of 8: 190 ohms is the total resistance of the two resistors.  Spread it around however you like using the buttons below the resistors.  For example, 100 and 90, or 180 and 10, or 190 and 0.
  • 8 of 8: When it's right, a green light will come on.  Close the box with the lever and an elevator will arrive to take you to the windmill.
