Consider an ideal 16.0 V emf source connected to a 15 Ω resistor, two ideal ammeters, and two 2.2 Ω light bulbs, as shown at right. If the 15 Ω resistor were replaced with an ideal wire (and everything else were unchanged), the brightness of light bulb 1 would:
A. increase.
B. remain the same.
C. decrease, but will still be lit.
D. be completely dead.
Answer:D
