Fault This article includes a list of references‚ but its sources remain unclear because it has insufficient inline citations. Please help to improve this article by introducing more precise citations. In an electric power system‚ a fault is any abnormal electric current. For example‚ a short circuit is a fault in which current bypasses the normal load. An open-circuit fault occurs if a circuit is interrupted by some failure. In three-phase systems‚ a fault may involve one or more phases and ground

Class Notes 1 1 Basic Principles In electromagnetism‚ voltage is a unit of either electrical potential or EMF. In electronics‚ including the text‚ the term “voltage” refers to the physical quantity of either potential or EMF. Note that we will use SI units‚ as does the text. As usual‚ the sign convention for current I = dq/dt is that I is positive in the direction which positive electrical charge moves. We will begin by considering DC (i.e. constant in time) voltages and currents

Lab Report 3: Electrical Properties of Ceramic Materials Lab III: Physical Properties of Materials By Will Paxton 3/5/07 Abstract The electrical properties of 5 different samples were studied. Characterization of these samples was through the dielectric properties‚ as this is a very important step. The capacitance was measured for each sample incrementally while heating them up to 135ºC. In a second part to the experiment‚ piezoelectric samples were studied‚ and their piezoelectric coefficient
