Find vo and io SolutionAns Vo due to 7 V source is Vo7 using

Solution

Ans)

Vo due to 7 V source is Vo₇ using inverting op-amp formula Vo=Vin*-Rf/R1

Vo₇=7*-10k/5k=-14 V

Vo due to 10 V source is Vo₁₀ using non- inverting op-amp formula Vo=Vin+*(1+Rf/R1)

V+=10*20k(20k+10k) voltage division

V+=6.667 V

Vo₁₀=V+*(1+10k/5k)=6.667*3=20 V

Vo₁₀=20 V

using super position theorem

Vo=Vo₇+Vo₁₀=-14+20=6 V

Vo=6 V

Io=Vo/RL=6/10k=0.6 mA

Io=0.6 mA
