Found in an Electronic Design from the 90's, this circuit simulates a 100 W resistor. The power transistor must match the desired current in the load under test.
With the coded activation of the relays, it is possible to control which of the 16 outputs...
The integrated circuit used in this application is not very common. Transistors and resistors...
This simple circuit makes use of neon lamps to indicate the voltage of a power grid. The lamps are...
