A Block A block in the shape of a rectangular solid has a cross-sectional area of 3.00 cm² across its width, a front-to-rear length of 15.4 cm, and a resistance of 945 . The material of which the block is made has 5.33 × 1022 conduction electrons/m³. A potential difference of 35.9 V is maintained between its front and rear faces. X (a) What is the current in the block? A (b) If the current density is uniform, what is its value? A/m² (c) What is the average or drift speed of the conduction electrons? m/s (d) What is the magnitude of the electric field in the block? V/m
