A 1.5 V flashlight battery, a 10 ohm resistor, and a flash?light lamp are available. How should the lamp be connected in a circuit so that it would glow the brightest?
A) Connect it in series with the resistor and battery so that the bulb is next to the positive terminal of the battery.
B) Connect it directly to the battery; don't use the resistor.
C) Connect it in parallel with the battery and the resistor.
D) Connect it in series with the resistor and battery so that the bulb is next to the negative terminal of the battery.

In this case, connecting the lamp directly to the battery without the resistor will result in the lamp glowing the brightest. The resistor would limit the amount of current flowing through the circuit, which would reduce the brightness of the lamp.
