rcuite, Cuments, and vontged Learning Goal: To detemine the voltage and currants for eloments in an eloctric circut. An electric dirouit contains circut dements connected togather in by conductors. Some typical elements in eloctric circuits include resistors, capacitors, inductors, and voltage sources. The behavior of cach eiement can be described in tems of the oument passing through the element and the voltage across the element. dge) Elactric cument is the time rate of fow of clectric charge in specified direction. Lat g(t) represent the net charge that has flowed through a surtace in a diraut diement or conductor. The oument is the time rate of change of the nat charge, 1(1) - Positive charge moving in the chosen direction and negative charge moving apposite the chosen direction are both positive ouments. Positive charge moving opposite the chosen direction and negative charge moving in the chosen direction are both nogative cuments. The units of charge are coulombs, C, and the units of current are amperes A, which are the same as coulombs per socond, Cis. The voitage associated with a cirout ciement is the enargy transfered per unt charge that flows through the element. Avoltage has a polarity botwoen the teminais of a circit element that indicates the diraction aof energy fow. a positive cument flows through a dirouit eiement trom the positive terminal to the negative teminal, then anergy is tranatemed into the circut dlement where is is absorbed or used to do useful work. If a positive cument filows from the negatve teminal to the positive terminal, then the circuit element is transteming energy to the ciectric charges. The units of voltage are voits, V, which are the same as joules per coulomb, JC.
