To determine which statement is false regarding the 'drift' of charge carriers, we need to evaluate the given statements and identify the incorrect one. Here are the statements:
1. Charge carriers in a conductor experience collisions with atoms and impurities, causing their random motion - This statement is true. In a conductor, charge carriers like electrons move in a random manner due to collisions with atoms and impurities present in the material.
2. In a direct current (DC) circuit, charge carriers move in a constant direction - This statement is also true. In a DC circuit, the flow of charge carriers is directed in a consistent path from the positive terminal to the negative terminal of the power source.
3. The average velocity of charge carriers in a conductor is known as the drift velocity - This statement is true. The drift velocity refers to the average net velocity of charge carriers in a conductor, considering their random motion.
Based on the given statements, it appears that all of them are true. Therefore, none of the statements is false regarding the 'drift' of charge carriers.
