Technician exam question T6A05
Subelement T6, ELECTRONIC AND ELECTRICAL COMPONENTS· Group T6A
What type of electrical component consists of conductive surfaces separated by an insulator?
- A.Resistor
- B.Potentiometer
- C.Oscillator
- D.Capacitor (correct answer)
WhyA capacitor is the type of electrical component that consists of conductive surfaces separated by an insulator. A capacitor is built from two conductive surfaces (plates) separated by an insulating material, the dielectric, the exact structure this question describes, answer D. A resistor (A) and potentiometer (B) are built to oppose or adjust current flow, not to sandwich conductors around an insulator, and an oscillator (C) is a complete active circuit, not a simple two-terminal part.
