RHOGreek letter "rho" (ρ). Used in the field of electricity and electronics to represent the specific resistance of a substance [4]. | ||
RHOMBIC ANTENNAA diamond-shaped antenna used widely for long-distance, high-frequency transmission and reception [10]. | ||
RIGID COAXIAL LINEA coaxial line consisting of a central insulated wire (inner conductor) mounted inside of a tubular outer conductor [10]. | ||
RIGIDITYThe tendency of the spin axis of a gyro wheel to remain in a fixed direction in space if no force is applied to it [15]. | ||
RING TIMEIn radar, the time during which the output of an echo box remains above a specified level [18]. | ||
RINGINGRF oscillations caused by shock excitation of a resonant circuit or cavity [18]. | ||
RIPPLE FREQUENCYThe frequency of the ripple current. In a full-wave rectifier it is twice the input-line frequency [6]. | ||
RIPPLE VOLTAGEThe alternating component of unidirectional voltage. (This component is small compared to the direct component.) [6] | ||
RL DIFFERENTIATORAn RL circuit in which the output is taken from the inductor [9]. | ||
RL INTEGRATORAn RL circuit in which the output is taken from the resistor [9]. | ||
