NettetFor example, the power cord for a lamp consists of metal wires inside a rubber insulator, and an electronic toy might have a plastic case that protects the circuit inside from damage. In this experiment, you will build a simple circuit with a battery and a lightbulb, and use it to test whether common household materials are conductors or insulators. NettetThe use of nonceramic and composite insulators in place of traditional porcelain and glass insulators for line insulation has become widespread in the last 20 years. Such …
