Vo = (-100k/100k)*1+(1+100k/100k)*{(-1)*(20k/(20k+20k))}.
= -1*1+2*(-1)/2.
= -1-1.
= -2 Answer.
= -1*1+2*(-1)/2.
= -1-1.
= -2 Answer.

R1 = 100K.
R2 = 100K.
Vo = R2/R1(V2-V1).
Vo = 100K/100K(-1-1).
Vo = 1(-2).
Vo = -2 Answer.
R2 = 100K.
Vo = R2/R1(V2-V1).
Vo = 100K/100K(-1-1).
Vo = 1(-2).
Vo = -2 Answer.

I think the answer should be 0 V.
Because the is not powered. So no amplification.

Since its a circuit of subtractor whose o/p voltage is = v1-v2= -2*v2 = -2*1 = -2.

Vo = (-RF/R1)V1 + (1+(RF/R1))V2'
= -1 + (1+1)(20*V2/40)
= -2 (ACCORDING TO ME..)
= -1 + (1+1)(20*V2/40)
= -2 (ACCORDING TO ME..)

[R3/(R1+R3][(R2+R4)/R2][V1]-[V2 (R4/R2)] is the formula. So it is 0V.

Vo = (-RF/R1)V1 + (1+(RF/R1))V2'.
= -1 + (1+1)(20*V1/40),
= -2.
= -1 + (1+1)(20*V1/40),
= -2.

Vo = RF(V2-V1)/R1.
Vo = (-1-1)100k/100k
Vo = -2.
Vo = (-1-1)100k/100k
Vo = -2.

Vo = -Rf/R1*V1-V2.
= -100/100*1-(-1) V.
= -2 V.
= -100/100*1-(-1) V.
= -2 V.

It is diff amplifier Vo = (v2-v1) = (-1-1) =-2.
