Question

Chapter 26, Problem 033

A block in the shape of a rectangular solid has a cross-sectional area of 2.72 cm² across its width, a front-to-rear length of 18.0 cm, and a resistance of 1060 ?. The block's material contains 4.59 × 10²² conduction electrons/m³. A potential difference of 36.3 V is maintained between its front and rear faces. (a) What is the current in the block? (b) If the current density is uniform, what is its magnitude? What are (c) the drift velocity of the conduction electrons and (d) the magnitude of the electric field in the block?
