Q2: A galvanometer has a current sensitivity of the order of 0.1 mA (full-scale deflection current) and a small internal resistance of about 500 ohms. To measure high currents, it was connected to multiple resistances in parallel (Shunt Resistors) with the galvanometer as shown in the figure. Find these shunt resistors (Ri through R3).
