Question

Include a written explanation of how you calculated the drift velocity.

Problem II. A voltage Vo is applied across a horizontal bar of length L, with a square cross- section, d on a side. A current I, is flows through the bar. Answer the following in terms of the quantities given. a) Indicate in the drawing the end of the bar that is at the highest potential b) Find the electric field in the bar under these conditions. Give both magnitude and direction. c) Find the resistivity of the bar. d) Indicate the direction of the drift velocity of the charge carriers. Estimate its magnitude. The density of charge carriers in this material is no

Answer 1

Here we apply concept of drift velocity and ohm's law.
