Extracted text: Q2. To determine the galvanometer's internal resistor Re and its maximum electric current Ic , corresponding to a maximum deviation of its needle, we mount it in series with a rheostat, as shown in the adjacent figure. İbre a Reosta When the needle makes a maximum deviation Vab = V1 = 5 V and R; = R1 = 80 kQ. When the needle makes ½ maximum deviation Vab = V2 = 2 V and R; = R2 = 60 kQ. When the needle makes 4 maximum deviation Vab = V3 = 2 V and R, = R3 . Galvanometre V Write the relationship between V1 , R1 , Rc and Ic . Write the relationship between V2 , R2 , Rc and Ic . Write the relationship between V3 , R3 , Re and Ic . Determine the values of Re and I . Determine the value of R3 . a) b) Answer:
