Which adjustment does temperature compensation make?

  • A.None
  • B.A voltage varying with engine speed, which prevents the output from rising excessively at high engine speeds
  • C.A higher voltage when cold and lower when hot
  • D.A higher voltage when hot, which compensates for the increased internal resistance of the battery at temperature

Answer: C

A cold battery accepts charge less readily so the voltage is raised, while a hot one would gas at the same setting. The compensation is around twenty millivolts per degree. Modern systems measure battery temperature directly. The shared behaviour explains why these belong together and the differences explain why both exist. Naming what changes and what stays the same is the reliable route through questions of this shape. Checking the units of each quantity catches a wrong formula before the arithmetic begins.
