WebThe resistor R1 limits the base current of the output transistor. It is not a shunt because this resistor does not turn the current into a voltage that controls anything, but simply limits the current according to Ohm's law. The small LED D2 has two functions. It is both an indicator of the instrument’s operation and most importantly, the ... WebThe circuit is therefore completed through a second resistor, termed the main shunt ; as with a potentiometric recording system the connexions are made to the ends of this resistor, thus enabling the corresponding voltage drop to be indicated.
