J = An electron is moving at a constant speed of 23.7 m/s on a circle of radius 3.89 m. o Express the circumference of the circle in terms of its radius, r. Express the time interval, T, for the electron to finish one circle in terms of the circumference and the speed. Express the current in terms of the fundamental charge, e. Calculate the numerical value, in amperes, of the current. A

answer sheet in the box on the front table. 1. A metallic conductor is carrying a current. The drift speed of the electrons in the conductor is 2.00 mm/s. The resistivity of the conductor is 2.00 x 10 .m. This conductor has 5.00 x 1028 electrons/m°. What is the magnitude of the electric field in the conductor (in V/m)?

An electric current in a conductor varies with time according to the expression I(t) = 90 sin (90πt), where I is in amperes and t is in seconds. What is the total charge passing a given point in the conductor from t = 0 to t = 1/120 s? The charge is the integral of the current. C Need Help? Read It Watch It
