Question

1. Calculate the number of free electrons in a copper conductor having a diameter of 0.064in and a length of 1000ft. 2. A current of 5A exist in a 10ohms resistance for 4 minutes. A) How many coulombs B) How many electrons pass through any section of the resistor in this time? Charge of e= 1.6x10^-19. 3. The electric charge that moves through a conductor varies in accordance with the equation q=800t, where q and t are given in coulombs and milliseconds, respectively. Calculate the current in Ampere. 4. Determine the total charge entering a terminal between t=2s, if the current passing the terminal is I= (3t^2-t)A
