The ________ depends upon the pressure of contact exerted on live wires.
Direct Answer
Option C: impedance
Electrical impedance, which is the opposition to alternating current flow, is significantly influenced by the pressure of contact on live wires. Poor contact pressure increases contact resistance, a component of impedance, leading to localized heating and potential arcing. Maintaining proper contact pressure is crucial for electrical system integrity and safety, preventing hazards.
