After killing all source equivalent resistance is R Open circuit voltage = v₁

The short circuit current across the terminal is

For the calculation of R_TH if we kill the sources then 20 Ω resistance is inactive because 5 A source will be open circuit

To determine RTHR_{TH}RTH​, the Thevenin equivalent resistance of the given circuit, follow these steps:

1. Turn off all independent sources:

   • The 2A current source will be open-circuited.
   • The 5V voltage source will be short-circuited.

2. Analyze the resulting circuit:

   • After turning off the sources, the 6Ω resistors are left connected in parallel.

Here's the process step-by-step:

1. Turn off the current source:

   • Open-circuit the 2A current source.

2. Turn off the voltage source:

   • Short-circuit the 5V voltage source.

After killing all source,

If we solve this circuit direct, we have to deal with three variable. But by simple manipulation variable can be reduced to one. By changing the LHS and RHS in Thevenin equivalent
