# Regulated Power Supply

I am supposed to simulate this circuit (regulated power supply 5V), however I am not understanding what's the point of the resistor R. Is it a load resistor? Cause i thought these needed to be before the regulator.

• yes. it's a load resistor. – Marko Buršič Apr 1 at 18:08
• @KingDuken: I don't see anything to do with current regulation in the OP's schematic. – Peter Bennett Apr 1 at 19:06

As you adjust $$\R\$$ in your simulation, you should be able to see the input voltage (across $$\C\$$) go up or down, but the voltage across $$\R\$$ should remain relatively constant.
