I think you need to do a little investigation of Ohm's Law and combining resistances in parallel.jdawg said:Does it go to zero? Why does that happen?
The Thevenin equivalent circuit is a simplified representation of a complex circuit that contains a single voltage source and a single resistor. It is used to model the behavior of a circuit for a specific load, making it easier to analyze and design.
To find the Thevenin equivalent circuit, you need to determine the Thevenin voltage and the Thevenin resistance. The Thevenin voltage is the open circuit voltage at the output terminals, and the Thevenin resistance is the equivalent resistance seen from the output terminals when all independent sources are turned off.
Isc stands for short-circuit current, which is the maximum current that can flow through the Thevenin equivalent circuit when the output terminals are shorted. It is an important parameter in determining the maximum power that can be delivered by the circuit.
To determine Isc, you can use the Thevenin resistance and the Thevenin voltage. Isc is equal to the Thevenin voltage divided by the Thevenin resistance. Alternatively, you can also find Isc by shorting the output terminals of the Thevenin equivalent circuit and measuring the current.
Finding Isc is important because it provides information about the maximum current that can be drawn from the circuit. This is useful for designing and analyzing the circuit, as it allows you to determine the maximum power that can be delivered and the stability of the circuit under different load conditions.
