For some reason I find immense difficulty in figuring out these circuits. I must be missing something somewhere
Here's my issue. I have this circuit:
And I need to find the Thevenins equivalent circuit. When I first got the problem I confidently threw some voltage divider equations around and got the thevenin voltage as 0.75V. But that's wrong. It's actually 0.5V. Why? Thats where I need help! If you could explain that to me I would be very thankful.
More info on what I did to get my answer.
First I used a voltage divider equation on the 200ohm resistors. That resulted in 1/2(3V) = 1.5V. Then I put that voltage in the next voltage divider equation with the 100ohm resistors, which came out as 1/2(1.5) = 0.75. It seemed so simple, but I went wrong. Where?
Someone suggested putting the two 100ohm resistors in series and solving from there but I'm not sure that's the right thing to do
