ASE A6 Electrical Electronics Practice Test
17. Which of the following statements are true about the diagram illustrated above?
- A. It is a schematic of an alternator.
- B. It contains 12 diodes and 4 resistors.
- C. Both A and B
- D. Neither A or B
Answer A is wrong. It is a schematic of an alternator. Vehicle manufacturers create diagrams of the entire vehicle that can be complex and difficult to sort through, so they're broken down into system-specific diagrams called block diagrams.
Answer B is wrong. Schematics are used in electronics; they contain standardized symbols to represent components in a circuit. The diagram above contains 12 diodes and 4 resistors.
Answer C is correct. Both A and B are correct.
Answer D is wrong. Both A and B are correct. The schematic contains diodes, resistors, a variable resistor, and symbols representing solid-state circuitry.
