Thevenin Equivalent: Solving Circuit Problems

Click For Summary
SUMMARY

The discussion focuses on calculating the Thevenin equivalent of a circuit, specifically addressing the open-circuit voltage. Participants clarify that no current flows through resistor R3 when the circuit is open, leading to a straightforward calculation of the open-circuit voltage. The consensus is that understanding the behavior of current in open circuits is crucial for determining Thevenin equivalents accurately.

I'm trying to find the Thevenin equivalent of the circuit on the left side and but having trouble in getting the open circuit voltage.

Does no current flow through R3 since that way leads to a dead end?

How could any current flow through R3?
There is no way to go for any current.
Therefore the open-circuit voltage is easy to calculate.

Yes, no current flows through R3 when the circuit is "open". If no current flows, what is the potential difference between the terminals of that resistor?
