Thevenin Resistance query
I have an amplifier model circuit where I've determined the load (speaker) voltage (using its peak power output and its resistance) and measured the open-circuit voltage.
How can I work out the ...

Idea behind Thevenin equivalent circuit
As i know, we find a thevenin equivalent resistance by finding open-circuit voltage and short-circuit current and then divide these two. I have looked on wikipedia and other sources but could not find ...

How do I calculate load resistance?
I'm here with yet another problem. This time I can't figure out what the question wants. I've calculated the Thévenin equivalent, however I can't work out how I should calculate the RL.
Is the load ...

Getting Thévenin equivalent when there's a current source only
I am stuck finding the Thévenin voltage in this circuit.
What I did first is remove the current source and replace it with an open circuit. After that I got the Thévenin resistance which is the ...

For the network shown in the figure, draw the corresponding Thévenin equivalent circuit and establish its parameters VT and RT
I can't find any examples online similar to this format, please help!
Attempt: RT = (2*5)/(2+5) = 10/7 = 1.429 k-ohms
VT = 8V + 8V = 16 V
Do you ignore the center resistor and just add the voltages ...

Confused about Thevenin’s Theorem
I have a hard time trying to understand why Thevenin’s Theorem is the way it is.
As per the diagram below, I understand why we take our “Thevenin resistance” that way. But as far as the voltage is ...
