The ends of a length of wire are labeleda and b. If the current in the wire is iab = -3A, are electrons moving toward a or b? How much charge passes through a cross section of the wire in 3 sec
Consider a three slab geometry, where each slab carries a uniform charge density and has equal width W in the z direction and in?nite extent in x and y directions. In slab 1, extending over W <
A curemt of 1600A exists in a recatangular (0.4 by 16cm) bus bar. The current is due to free electrons moving through the at an avg velocity V m/s. If the concentration of free electrons is 10^29
Two such wires are connected to the load. The wires run parallel to each other with a separation of 1mm. The second wire carries the return current. If the current flowing is again 13A DC, estim
Two electronics students are discussing electrical units. Student A says that electrical power is measured in units called coulombs. Student B says that the abbreviation 400 k stands for 400,000
