70% to passWhat is the purpose of the capacitor within component "5" of the circuit shown in figure "B" of the illustration? Illustration EL-0081
Acounteract the inductive reactance in the circuit
Bdischarge the neon within the envelope
Cprolong the life of the component's contacts
Dstore power to operate the circuit should "D" open
AI Explanation
The correct answer is C) prolong the life of the component's contacts. The capacitor in component "5" of the circuit shown in figure "B" of illustration EL-0081 is used to prolong the life of the component's contacts. When the contacts open or close, the capacitor helps to absorb the inductive spike or arc that can occur, reducing wear and tear on the contacts and extending their usable lifespan. The other answer choices are incorrect because: A) the capacitor is not used to counteract inductive reactance, B) it is not used to discharge a neon envelope, and D) it is not used to store power to operate the circuit if another component opens.
