What is a linear conductor? Discuss the conditions under which a metal does not behave as a linear conductor.
A linear conductor refers to a material that follows Ohm's Law, which states that the current passing through it is directly proportional to the applied voltage, given a constant temperature. In other words, the relationship between current (I), voltage (V), and resistance (R) is linear, and the material _______ __________ _____ _________ ________.
