Bitesize conductors
WebConductors, on the other hand, cannot hold the charge, as the electrons can move through them. Electrical forces A charged object will experience non-contact force from another charged object.... WebInsulating materials are bad conductors and so this reduces the heat loss by conduction. The material also prevents air circulating inside the cavity, therefore reducing heat loss by convection.

For example, a thermistor’s resistance depends on its temperature.... WebCircuits have to let electrical current flow through them easily. Materials that let electricity flow through them easily are called conductors. Most metals are conductors; however, materials that prevent electricity from flowing are also important for circuits. These materials are called insulators. Most rubbers and plastic are insulators.
