Which of the following types of linear voltage regulator operates by loading the unregulated voltage source?
A constant current source
A series regulator
A shunt current source
A shunt regulator✓Bonne réponse
Explication
A shunt regulator sits across the load and conducts whatever current the load does not take, so the total current drawn through the series dropping resistor stays roughly constant. Regulation is therefore achieved by loading the unregulated source.
