Final answer:
The Bakelite coating serves as an electrical insulator for the conducting rod.
Step-by-step explanation:
The Bakelite coating serves as an electrical insulator for the conducting rod.
The conducting rod, being made of a conducting material, allows the flow of electricity. However, in certain applications, it is necessary to prevent the flow of electricity through the rod. By applying the Bakelite coating to the rod, it creates a layer of non-conductive material that acts as a barrier and prevents the flow of electrical current.
For example, if the conducting rod is used in an electrical circuit where it needs to be isolated from other conductive components, the Bakelite coating ensures that there is no unwanted electrical contact.
Bakelite, a synthetic plastic patented on December 7, 1909, has electrical nonconductivity and heat-resistant properties, making it an excellent choice for insulating electrical conductors. Bakelite's use in electrical insulators, among other applications, is due to its ability to prevent electrical current from escaping the conductor and to protect against high temperatures that may arise during the operation of electrical devices.
