**Glossary J**

**JFET:** Junction Field Effect Transistor.

**Joule:** The basic unit of thermal energy.

**Junction:** The join of two conducting materials.

**Junction:** The point in a thermocouple where the two dissimilar metals are joined.

**Glossary K**

**K:** When referring to memory capacity, two to the tenth power (1024 in decimal notation).

**Kelvin:** Symbol K. The unit of absolute or thermodynamic temperature scale based upon the Celsius scale with 100 units between the ice point and boiling point of water. 0°C = 273.15K (there is no degree (°) symbol used with the Kelvin scale).

**Kilowatt (kw):** Equivalent to 1000 watts.

**Kilowatt Hour (kwh):** 1000 watthours. Kilovolt amperes (kva): 1000 volt amps.

**Kinetic Energy:** Energy associated with mass in motion, i.e., 1/2 rV2 where r is the density of the moving mass and V is its velocity.

**KVA:** Kilovolt amperes (1000-volt amps).
