can anyone explain this circuit simplification
When a battery is ran across ab, the 20 and 10 ohm resistors are in parallel with one another which I sorta understand (but if you can explain that, it'd be great), but I don't get how their equivalent resistance (30 ohm) is in series with the 15 ohm resistor
I feel like if I could draw it I might get it but I cant even visualize it because fuck triangles
please help im about to shoot msyelf
