A. Short answers questions: 1. Kirchhoff's current and voltage laws depend on conservation of energy.Both of Kirchhoff's laws can be understood as corollaries of the Maxwell equations in the low-frequency limit. They are accurate for DC circuits, and for AC circuits at frequencies where the wavelengths of electromagnetic radiation are very. An electric current, I, is the rate at which net charge (∆Q) flows through a surface area A Current's units = C/S and often written as A (Ampere) Although current carriers (i.e., charges) could be +or -, the direction of current will be in the direction of a + charge flow (i.e.,clockwise) I + A Electrons are actual current.
