ASE A6 Electrical Electronics Practice Test
31. There’s an open at point A in the heated seat circuit above. Technician A says this will only affect the heating element in the backrest. Technician B says the two heating elements are part of a parallel circuit. Who is correct?
- A. Technician A
- B. Technician B
- C. Both A and B
- D. Neither A or B
Answer A is wrong. Point A is the wire leading from the seat cushion to the backrest. An open in this wire will disable both elements.
Answer B is wrong. They run in series. This is different from parallel circuits where one of the components can fail without affecting the others.
Answer C is wrong. Neither technician is correct.
Answer D is correct. Learn more about this circuit in the read more section.
