Notes
Discuss with you students how much current can be drawn across a resistor. The resistors on
the box is about 5W. If you apply 3V across 1-ohm resistor (left top) the resistor will over
heat. Several of our boxes show indication, that this had happened. Be careful this not to
happen. Make sure to check maximum voltage you can draw across each resistors.
For ammeters use 10A max connection.
