Androgen

Tantalum and Niobium-Based Capacitorsn the introduction of vector analysis into several courses. The use of vector analysis comes rather naturally, since many of the quantities encountered in the modeling of physical phenomena are vector quantities; examples of such quantities are velocity, acceleration, force, electric and magnetic fields, and heat flux.
