Which cable specification does a starter supply require?

  • A.A flexible conductor only
  • B.A screened cable, which prevents the heavy current from inducing interference within the adjacent wiring of the vehicle
  • C.A large cross section to limit voltage drop at high current
  • D.A high voltage insulation rating, which is required because the starter operates at a higher voltage than other circuits

Answer: C

Hundreds of amps through a thin conductor would waste most of the available voltage, so cable of many square millimetres is used. Flexibility genuinely matters where the engine moves relative to the body, which makes the third option a real secondary requirement. Naming what changes and what stays the same is the reliable route through questions of this shape. Reading the definition literally, rather than recalling a summary, avoids the usual confusion.
