Found in a Hands On Electronics from the 80's this circuit allows the reading of low resistances in a common multimeter. The circuit consists of a constant current source.
The circuit bellow uses two NPN transistor to drive heavy loads up to some amperes. The maximum...
The gain of this amplifier is given by the 120k resistor, which can be changed depending on the...
Here we show how a Constant Current Source can be created in the Multisim Blue using a common BJT...
