The circuit schematic attached is one for a power supply. This power supply is restricted to 5 amps. However, I am having a difficult time understanding the calculations on how the resistor values are chosen to achieve this limit of 5 amps.
When using the simulator's oscilloscope, the limit is closer to 6 amps. Regardless, there has to be a way to determine this value of 5-6 amps.
The first transistor in the circuit is meant to do most of the current limiting. Can someone explain to me how the resistors affect the current allowed to flow to the load?
