Question

how can you test a conductor? use a circuit with a bulb heat the material dissolve it in water freeze the material what role do conductors play in circuits? block current provide a path for current store energy prevent electricity flow what do insulators do in circuits?* conduct electricity prevent unwanted current flow power the circuit heat the circuit

Explanation:

1. For testing conductors: A circuit with a bulb works because if the material conducts, current flows and the bulb lights up, confirming conductivity.
2. For conductors' role: Conductors have free charges that allow electric current to travel through them, so their core role is providing a path for current.
3. For insulators' role: Insulators have no free charges, so they stop unwanted current flow, which protects circuits and users.
