The unit for reactance the ohm.
Rectifier device circuit that converts alternating current direct
current.
Reactance The opposition alternating current resulting from circuit
inductance and capacitance. RAM requires the continual application
of power retain information.The unit for
reactive power the var.

Reduced-Voltage Starter type motor starter that applies less than the full-line
voltage three-phase induction motor while starting.
Resistance symbolized “R” and measured ohms.
There are variety reduced-voltage starters. Some types
use electromechanical components and others use electronic
components.
. Electronic reduced voltage starters are often
referred solid-state reduced voltage starters soft
starters.
Read Only Memory (ROM) Usually refers type semiconductor memory often used
for permanent storage data programs that not change
