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
