# Thevenin Equivalent of circuit

I have a circuit that looks like the following. It appears to be simple-

What's the thevenin equivalent? I can't seem to simplify it as there are no common nodes that any of the resistors connect.

• I would redraw this circuit first to clearly see what is parallel to what Jun 30 '20 at 17:35
• R5 to R1 is as R4 to R2 - redraw to make the image simpler - this always helps. Jun 30 '20 at 17:44
• If you redraw your schematic you will find that it is similar to a "Wheatstone bridge" (not invented by Wheatstone who only popularized another's invention) except that there is a resistor where a source usually is placed. It's a classic case suggesting that you memorize the $\Delta-Y$ conversions (both directions may be worth memorizing.) But it can also be solved out using nodal analysis, too. Are you familiar with nodal?

• As others say, you can re-draw this to make it more clear. Also, this problem is often given with further condtions, like R1=R2=R4=R5. If you were given that information, you can simplify the circuit even further with a clever trick. Jun 30 '20 at 20:52
