Definition of "VAC" |
Volts ac Vacuum evaporation The deposition of thin films of semiconductor material by the evaporation of elemental sources in a vacuum. / Vacuum Assisted Closure, Volt(s)Alternating Current , / VAC power - it is just AC power. When you see 110 VAC on an appliance, it means 110 volts AC power. Voltage is a measure of "circuit pressure." It refers to how hard the electricity pushes through a circuit. The voltage helps to determine the amperage–the amount of electricity flowing through the circuit every second. The higher the voltage, the harder the electricity pushes on a circuit and the more electricity flows through it. AC is also measured in frequency–how fast it changes direction. Most AC power is at 60 hertz, which means that it changes from negative to positive to negative again 60 times a second. |
