Thevenin Equivalent Example Problem

This example problem uses Thevenin's theorem to determine a Thevenin equivalent circuit for a DC electrical circuit with two voltage sources and a few resistors. Note that this video solves the example problem, but does not give a detailed explanation for Thevenin's theorem.

00:13 - Problem definition
00:19 - Step 1: Identify part of circuit to Thevenize
00:35 - Step 2: Label port
00:53 - Step 3a: Set voltage sources to 0V
01:53 - Step 3b: Calculate RTh (Thevenin resistance)
02:42 - Step 4: Determine VTh (Thevenin Voltage)
03:03 - : Use superposition
03:24 - : 10V source VTh calculation
04:40 - : 24V source VTh calculation
05:40 - : Put 10V and 24V source calculations together
06:25 - Thevenin equivalent circuit
07:01 - Calculate V(load) and I(load)
08:33 - Power of Thevenin

All over youtube, this is the only channel whose explanation is beginner friendly.

I remember when I was in college (about 35 years ago) attending the Electricity 101 class, all seemed so cryptic and confusing but you explain just in ten minutes what took me days to understand, and everything is so clear that I wish I had a teacher like you. Awesome. Thank you.

I love how you explain your answer for this problem. I hope you can create more example problems concerning different theorems (Branch current, maxwell, kcl/kvl, nodal analysis, superposition, thevenin and norton's).

Wait for the RTH step how is 10k in parallel with 2k?

[M.V.T.H.]

thanks alot this video is so much easier to understand than most

[KAFKUBA]

I'm lost and I've been an engineer 40 years... never needed this cause I never could believe it

[solosamuraiz]

How is the 2k in parallel? It contadicts other videos. If its a speci direction due to removing Vs, thsy should be noted

[robertbatista]

Excellent explanations. Knowing that there are any number of ways to solve the ckt, the simpler (thus faster) method instead of Superposition would have been to use “Special Thevenin” without the 4K and then to stick it back in to come up with a final Vth answer. He could even have left the 4K in and used Millman for a quicker solution.

Just wondering, is VL the same as VAB? What's VL analyzing for? I was thinking VL should be equal to VAB so that their voltage shall be the same...

[mikhailduplessis]

no one gonna talk about how he's writing backwards?

[ankitbazigar]

Thank you for this precious video Now I understand how to slove complex circuit thevnin theorem

[ElelusivebudgieNor]

So i am confused about how the thevenin voltage is between terminals A and B, but when you re-insert the load resistor in between these two terminals, the thevenin voltage does not drop across the load resistor. May you explain this to me? thanks

[marq]

I see why 4k||10k but wouldn't the result be in series with the 2k resistor? ((4||10)+2)

[tafadzwamunhuweyi]

Thank you so much I understood perfectly

[aliyasser]

What will be the Vth if it was between 10k ohm ?

[sard_]

damn best explanation i got for this,

[foryourculture_]

4:05 How did you get 2.857K as the combonation of the 10K and 4K?

[benashfordeagland]

Thankyou, that was brilliantly explained!

[ultrongaming]

Is the VAb solved by using superposition theorem?

[jethrobo]

Wow... I wish YouTube (and ElectronX Lab) would have been around when I was in EE (40 years back).
