A girl throws a 0.1 kilogram ball at a wall. The ball hits the wall perpendicularly with a velocity of 5 meters per second and then bounces straight back with a velocity of 4
Q. If 6.25 X 10 18 electrons flow through a given cross-section in unit time, find the current. Solution: Current I = q / t = ne / t = (6.25 X 10 18X 1.6 X 10 -19) / 1 = 1 A
As the name indicates, the dielectric of this type of capacitor is a ceramic. The basis of ceramic material is mainly barium titanate or a similar material, but other ceramic subst
Self inductance: When current through a coil changes, the changing flux induces an emf that opposes the current flow. This emf is the result of self inductance and is called '
