Technician A says that the physical distance between the two wires on a twisted wire pair determines their capacitance,with capacitance decreasing as the wires become further apart,accounting for the fact that replacement is usually preferred over repair.Technician B says that the insulation wrap over a twisted wire pair also defines the capacitance which explains why it should never be replaced with ordinary wire.Who is correct?
A) Technician A only
B) Technician B only
C) Both A and B
D) Neither A nor B

Question

Quizplus · Accepted Answer

Both technicians are correct. Technician A is correct in stating that the physical distance between two wires in a twisted pair affects their capacitance, with greater distance resulting in lower capacitance. This is a fundamental principle of capacitance, which is influenced by the distance between conductors. Technician B is correct in stating that the insulation wrap over a twisted wire pair affects its capacitance. The type of insulation and its thickness can influence the capacitance between the wires, which is why specific types of insulation are used for twisted pair cables to achieve desired electrical properties. Replacing it with ordinary wire could alter these properties, affecting the cable's performance.
