"j" to "knee voltage" |
|
- j
A prefix used to indicate an imaginary number. (Operator j)
- jack
- Socket or connector into which a plug may be inserted.
- JFET
- Abbreviation for "Junction field effect transistor".
- joule
- The unit of work and energy.
- junction
- Contact or connection between two or more wires or cables. The area where the p-type material and n-type material meet in a semiconductor.
- junction diode
- diode. A semiconductor diode in which the rectifying characteristics occur at a junction between the n-type and p-type semiconductor materials.
K
- 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.
- Kirchoff'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.
- Kirchoff'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.
