1 Answer

Final answer:

Plastic is important around the metal pins of plugs because it acts as an insulator, preventing electric charge from escaping outward.

Step-by-step explanation:

Plastic is important around the metal pins of plugs because it acts as an insulator, preventing electric charge from escaping outward. The conducting wires in a plug allow electrons to move freely through the cables, and the plastic coating provides a protective barrier to prevent electric shocks and short circuits. Without the plastic insulation, there would be a greater risk of electrical accidents and damage to the plug and electrical devices.
