Multiple-Choice Problem 3.

1. A.    The reading in ammeter A, is greater than the reading in A₂ because current is lost in the resistor.
2. B.     The two ammeters have exactly the same readings.
3. C.     The voltmeter reads less than 25 V because some voltage is lost in the resistor.
4. D.    The voltmeter reads exactly 25 V.
