There is a series type ohmmeter, designed to operate on a 6 V battery. The galvanometer has an internal resistance of 2000 ohms and requires a current of 100 μA for full full scale deflection. The value of R1 is 49 k ohms. If the battery voltage has dropped to 5.9 V, determine the necessary value of R2 to zero the meter; b) According to the conditions indicated in the previous paragraph, an unknown resistance is connected to the meter giving a deflection of 60%. Calculate the value of the unknown resistance.
