ERROR SIGNAL(1) In servosystems, the signal whose amplitude and polarity or phase are used to correct the alignment between the controlling and the controlled elements. (2) The name given to the electrical output of a control transformer [15]. |
EUTECTIC ALLOYAn alloy that changes directly from a solid to a liquid with no plastic or semiliquid state [14]. |
EUTECTIC SOLDERAn alloy of 63 percent tin and 37 percent lead. Melts at 361o F [14]. |
EXCITATION VOLTAGEThe supply voltage required to activate a circuit [15]. |
EXCITING CURRENTThe current that flows in the primary winding of a transformer when the secondary is open-circuited; it produces a magnetic flux field. Also called magnetizing current [2]. |
EXCLUSIVE ORA function whose output is a 1 if one and only one of the input variables is a 1 [13]. |
EXCLUSIVE-OR GATEA gate that produces a logic 1 output when the inputs are different, but not when they are the same [13]. |
EXPONENTThe numeral written in superscript (102) which indicates the power to which the base is to be raised [13]. |
EXPRESSIONA validated series of variables, constants, and functions that can be connected by operating symbols to describe a desired computation [13]. |
EXTERNALLY EXCITED METERA term used to describe meters that get their power from the circuit to which they are connected [16]. |
