Insulating materials have the function of
A. Preventing a short circuit between conducting wires
B. Preventing an open circuit between the voltage source and the load
C. Conducting very large currents
D. Storing very high currents
Answer: Option A
Solution(By Examveda Team)
Insulating materials are used in electrical and electronic systems to prevent the flow of electric current between conducting wires or components. They serve as barriers that hinder the movement of electrons and the flow of electricity. The primary function of insulating materials is to prevent unwanted electrical connections, such as short circuits, that can lead to electrical hazards and malfunctions.Among the options provided, the correct answer is Option A: Preventing a short circuit between conducting wires. Insulating materials help maintain the separation and isolation of conducting elements to ensure that current flows only where intended and to prevent accidental connections that could lead to short circuits and electrical failures.
Therefore, the correct answer is Option A: Preventing a short circuit between conducting wires.
