A galvanometer with a coil resistance of 16.3 is used with a shunt resistor to make a nondigital ammeter that has an equivalent resistance of 0.817 . The current in the shunt resistor is 3.97 mA when the galvanometer reads full scale. Find the full-scale current of the galvanometer.
A galvanometer of resistance 100 Ω gives full-scale deflection when its current is 1.0 mA. It is used to construct an ammeter whose full-scale reading is 100 A. If the shunt resistor consists of a piece of 10-gauge copper wire (diameter 2.59 mm), what should its length be
The coil of wire in a galvanometer has a resistance of RC = 75.0 Ω. The galvanometer exhibits a full-scale deflection when the current through it is 0.200 mA. A resistor is connected in series with this combination so as to produce a voltmeter. The voltmeter is to have a full-scale deflection when it measures a potential difference of 14.0 V.
