A certain voltage is applied to a copper wire and to a germanium wire of the same thickness and length. how will the current in the two wires compare?


Answer : The current will flow more easily and quickly through the copper wire, on application of voltage because copper is a metal which is good conductor of heat and electricity. In case of germanium it is a semi-conductor means it will behave as a conductor under certain circumstances. So if we take same length and same thickness of both the wires, current is more likely to flow through the copper wire than the germanium wire.
