To convert a galvanometer into a voltmeter with specified ranges, we need to calculate the required series resistance for each voltage range. Let's break down the solution step by step. ### Step 1: Determine the maximum deflection current (I_G) of the galvanometer. The maximum deflection current can be calculated using the formula: \[ I_G = \text{Number of divisions} \times \text{Sensitivity} \] Given: - Number of divisions = 50 ...
