Electrical Definitions |
RACE : A condition in a logic network in which the differences in propagation times through two or three more signal paths in the network can produce an erroneous output. |
Radar : Acronym for radio detection and ranging, a system that uses beamed and reflected RF energy for the detection and location of objects as well as for measuring distances or altitudes. |
Radio Signals : A carrier in the RF range that is modulated by an electromagnetic signal. |
Radio Technique : Techniques involving simple and advance principles in radio reception,selection,detection,transmission and modulation of radio waves. |
Radix : The base of number system.The number of digits in a given number system. |
Rectification : The conversion of an alternating current into a unidirectional current. |
Rectification Efficiency : It can be defined as the percentage of input ac power that is converted into useful dc output power. |
Reed Relay : A device based on the fact that an electric current passing through a coil of wire produces an electromagnet with the ends of the coil having opposite magnetic polarities. |
Reflector or Repeller : The electrode at negative potential with respect to the cathode which reverses the direction of the electron beam. |
Registers : Registers are digital circuits used for the temporary storage and shifting of information. |
Relay : An electrical device in which one electrical phenomenon(current,voltage,etc.) controls the switching on or off of an independent electrical phenomenon. |
Resistors : A device that offers resistance to flow of electric current measured in ohms. |
Rheostat : A variable wire wound resistor is known as a rheostat. |
