AC
Alternating current, an electric current that has one polarity during part of the cycle and the opposing polarity during the other part of the cycle. Residential electricity is AC.

Apparent Power
Apparent Power comprises reactive power and active power and is the product of the current and voltage. Apparent Power is expressed in either "megavolt amperes" (MVA) or "kilovolt-amperes" (KVA).

Balanced Load
A balanced load is an AC power system where two wires and two conductors are used and the current and voltages in each conduct are equal.

AC Power
Baseload
The baseload is the minimum level of power required by a given criteria either at a steady rate or over a specified amount of time.
Boost Converter
A boost converter power supply steps up and input voltage to higher, but still regulated levels.

Cable Tester
Cable testers are electronic devices used to test the integrity of electrical points in a wired assembly or cable.
Capacitor
Abbreviated as C (as in LCR). A capacitor is a passive component comprised of two conductors separated by a dielectric. A capacitor stores charge, blocks DC flow and allows AC flow based on frequency and capacitor design

Capacitance
The ratio of charge on either plate of a capacitor to the potential difference (voltage) across the plates. When a voltage is applied, current flows immediately at a high rate and then decays exponentially toward zero as the charge builds up. If an AC voltage is applied, an AC current appears to flow continuously because the polarity of the voltage is reversed at the frequency of the applied voltage. The waveform of this current is displaced in time from the applied voltage by 90°.

Charging Current
An insulated product exhibits the basic characteristics of a capacitor. Application of a voltage across the insulation causes a current to flow as the capacitor charges. This current instantaneously rises to a high value as voltage is applied then exponentially decays to zero as the DUT becomes fully charged. Charging current decays to zero much faster than dielectric absorption.
