2. An electrician experienced a mild shock when he accidentally touched a wire carrying 5.0 A for 1.5 s.  a. How many coulombs of charge flow through the electrician?  b. How many electrons constitute the given current?

Activity 2 Directions: Solve for the given problems. Show your complete solutions. Express your final answers into 3 significant figures. 1. Silver is composed of 5.8 x 1028 free electrons per cubic meter. If a silver wire with a diameter of 1.8 mm can allow charges of 360 C to flow in 1 hour, a. What is the current in the conducting wire? b. What is the magnitude of the drift velocity of the electrons in the conducting wire? 2. A wire has a radius of 1.90 mm. If the current in the wire is 6.14 A, the drift velocity is 4.86 x 10-5 m/s. What is the concentration of free electrons in the metal?
