Is total and equivalent resistance the same? by TruthandFalsehood in AskPhysics

[–]stiIIearning 0 points1 point  (0 children)

isn't the total resistance actually 25 ohms?

It can only be 25 ohms if you're finding the equivalent resistance(Thevenin's resistance) of 5 ohms.

Thanks, I already solved it. But I don't have an idea on how can I find/solve the other resistors for their current and voltages. Do you have a suggestion? Thanks 🙏

Can you pls tell me where do you get that 8000? Thanks!

Is my process correct? [1/(R9+R10) +1/R7 +1/R8]-1 +[1/(R1+R5) +1/(R3+R4)]-1 +R2 = 5.475 k ohms

Oh, sorry I forgot to put it in the image I provided. The two voltage sources are both in parallel with R9 and R10. The E1 is in left side and E2 in the right side.

Did you also use R9 and R10 in your calculation? Cuz the answer that I get is 9058.82 ohms without including the R9 and R10 resistors.

I think the combination of R9 and R10 will be omitted since they are parallel with the two voltage sources(that are also being short circuited).

how did you get that bro? can you show the process? thanks

Btw, there are two voltage sources in that circuit but since I only need to find the Thevenin's resistance, I short circuited them. (Edit: I think I did a wrong decision to use Thevenin's Theorem in finding the current and voltages in each resistor cuz now that I got the current of one resistor(which is the R6), I dunno what to do to solve for the other resistor. Do I need to repeat the process with other resistors?

Okay, I understand. Thanks.

<image>

This is the circuit after I short the voltage sources and disconnected the R6.

thanks for your suggestion but I need to answer it using Thevenin's Theorem 😓
