What electrical hazard, if any, does the starter battery in a vehicle present?
- A None, given its low voltage
- B High electromagnetic fields
- C Possibility of electric shock
- D High short-circuit current
Correct answer: D — High short-circuit current. From the official ISED question bank, verified word for word.
Why
A vehicle starter battery holds a low voltage that cannot push enough current through your skin to cause a shock, but it can deliver a massive surge of electricity if a metal tool accidentally bridges its terminals. The full explanation — and one for every question — is in Pro.
