What is the contribution of Eint to the output voltage Vout? 2. Relevant equations 3. The attempt at a solution To calculate the contribution of Eint, I removed the other two voltage sources. Then, I divided them into three potential dividers, giving me: Vbody= (ZC2/ZC2+ZC1) x Eint; V1=(Zin1/ZB1+Zin1) x Vbody; and V2=(Zin2/ZB2+Zin2 )x Vbody Lastly, Vout= Vbody- V1-V2. Is this method valid?
