kilo - Metric prefix for 1000. (103).
kilovolt-ampere - 1000 volts at 1 ampere.
kilowatt-hour - 1000 watts for 1 hour.
kilowatt-hour meter - A meter used by electric utility companies to measure the amount of electric power used by a customer.
kinetic energy - Energy associated with motion.
Kirchhoff"s current law - The sum of the currents flowing into a point in a circuit is equal to the sum of the currents flowing out of that same point.
Kirchhoff"s voltage law - The algebraic sum of the voltage drops in a closed path circuit is equal to the algebraic sum of the source voltages applied.
knee voltage - The voltage at which a curve joins two relatively straight portions of a characteristic curve. For a PN junction diode, the point in the forward operating region of the characteristic curve where conduction starts to increase rapidly. For a zener diode, the term is often used in reference to the zener voltage rating.
