(a). A silver wire 6.6 mm with diameter in which 3.6 ampere current passing through. Calculate how many coulombs of electric charge flows from silver wire in 3.0 hour. (b). The thin copper wire with radius of 1.3 mm is wound into a torus shaped coil as revealed in figure. From copper wire 8.75 x 10-2 ampere electric current passing though in 4800 sec. Number of free electrons per cubic meter in copper wire is 5.8 x 1028. Calculate magnitude of electron’s drift velocity in the diameter of copper wire.
