Unformatted text preview: a “three-scale” voltmeter whose binding posts are marked +, 3.00 V , 15.0 V , and 150 V . When the meter is connected to the circuit being measured, one connection is made to the post marked + and the other to the post marked with desired voltage range. Resistance of the moving coil, R G , is 40.0 Ω and a current of 1.00 mA causes it to deflect full scale. Find resistances R 1 , R 2 , and R 3 , and the overall resistance of the meter on each of its ranges....
