What was the experimental value of the galvanometer current $I_G$ measured in your laboratory session?

Solución: $6{,}96$ mA / $0{,}00696$ A

Under what circumstances can the condition $I_G = 0\text{ A}$ occur? If this condition can be achieved, explain what circuit modifications or parameter settings must be made.

Solución: Balanced bridge condition: $\frac{R_1}{R_2} = \frac{R_3}{R_4}$ so that $V_A - V_B = 0$ / Open circuit condition: branch disconnected or $R \to \infty$.
