Match each measurement with what it assesses.

List I

A. Specific gravity

B. Voltage drop across a terminal

C. Parasitic drain

List II

P. quality of a connection

Q. state of charge of a cell

R. current with the vehicle off

Select the correct match.

  • A.A-R, B-P, C-Q
  • B.A-Q, B-R, C-P
  • C.A-Q, B-P, C-R
  • D.A-P, B-Q, C-R

Answer: C

Specific gravity reads the state of charge, volt drop under load exposes a poor connection, and parasitic drain measures what is left running. Each is a distinct diagnostic with its own acceptance figure. Reading the definition literally, rather than recalling a summary, avoids the usual confusion. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision. Naming what changes and what stays the same is the reliable route through questions of this shape.
