Final answer:
To find the Thevenin equivalent of circuit 2 at nodes a and b, calculate the open circuit voltage and the equivalent resistance.
Step-by-step explanation:
To find the Thevenin equivalent of circuit 2 at nodes a and b, follow these steps:
- Calculate the open circuit voltage (Voc) by removing the load and calculating the voltage across nodes a and b.
- Calculate the equivalent resistance (Req) by shorting all voltage sources and finding the total resistance seen from nodes a and b.
- The Thevenin equivalent consists of Voc as the open circuit voltage and Req as the equivalent resistance.
