ASVAB Full-length Test
In electrical wiring, which of the following are proportional?
the diameter of the wire and the amount of the current
the length of the wire and the amount of the current
the diameter of the wire and the amount of the voltage
the length of the wire and the amount of the voltage
Detailed Explanation
Current flow through a wire increases the temperature of the wire. If too small a wire is used, the wire will heat up causing a loss in conductivity and possibly a fire. The thicker in diameter a wire is, the more current it can carry without overheating.
