R
RLC CIRCUITAn electrical circuit that has the properties of resistance, inductance, and capacitance [2]. |
RMSAbbreviation of root mean square [2]. |
ROOT MEAN SQUARE(RMS)—The equivalent heating value of an alternating current or voltage, as compared to a direct current or voltage. It is 0.707 times the peak value of a sine wave [2]. |
ROTARY CAPA spark gap, similar to a mechanically driven rotary switch, used to discharge a pulse-forming network [12]. |
ROTARY SWITCHA multicontact switch with contacts arranged in a circular or semicircular manner [3]. |
ROTATING FIELDThe magnetic field in a multiphase ac motor that is the result of field windings being energized by out-of-phase currents. In effect, the magnetic field is made to rotate electrically rather than mechanically [5]. |
ROTATING JOINTA joint that permits one section of a transmission line or waveguide to rotate continuously with respect to another while passing energy through the joint. Also called a rotary coupler [11]. |
ROTOR(1) The revolving part of a rotating electrical machine. The rotor may be either the field or the armature, depending on the design of the machine [5]. (2) The rotating member of a synchro that consists of one or more coils of wire wound on a laminated core. Depending on the type of synchro, the rotor functions similarly to the primary or secondary winding of a transformer [15]. |
RPKThe symbol used to represent the resistance between the cathode and plate of a tube [6]. |
RUNNING OPENThe teletypewriter condition where the type hammer constantly strikes the type box but does not print or move across the page [17]. |
