Problem #1 0 1 2 3 4 5 6 + - Y Ohm resistor Note: The resistance of the coil (electromagnet) inside this ammeter is : 1000 Ohms DC Ammeter: 0-6 mA We want to use the ammeter, shown below, to construct a voltmeter that can measure voltages between 0 Volts and 60 Volts; where 60V corresponds to a full scale reading (6mA) on the meter. What value to we need to use for Y?
