Consider the circuit shown in Fig. The circuit uses an ideal operational amplifier. Assuming that the impedances at noodes A and B do not load the preceeding bridge circuit, calculate the output voltage Vo.
when $${R_a}\, = \,{R_b}\, = \,{R_c}\,{R_d}\,$$ ohms.
when $${R_a}\, = \,{R_b}\, = {R_c}\, = 100$$ ohms and $${R_{d\,}}\, = \,120$$ ohms.
