Q1. Why is it bad practice to connect many high-power appliances to one thin extension cord?
Answer: Total current may exceed safe capacity and overheat the cord
Explanation: Each high-power appliance draws significant current, and connecting many in parallel means the extension cord carries the sum of all their currents; if this total exceeds the cord's rated capacity, resistive heating in the thin wires can cause insulation to melt or ignite. This is the leading cause of electrical fires from overloaded extension cords.
