Unformatted text preview: voltage source, and a galvanometer' A Wheatstone biidge js balanced when the resjstors obey Eq. 3 33, resulting in a galvanometer reading of 0 A. (See page 71.) . A circuit with three resistors connected in a A configuration (or a ?]' configuiation) can be transformed into an equivalent circuit in which the ttrree resistors are Y connected (or T connected). The AtoY transformation is given by Eqs.3.443.46; the YtoA hansformation is given by Eqs. 3.473.49. (See page 74.) . An ammeter measurcs current and must be placed in series with the curent being measured.An ideal ammeter has zero internal rcsistance and thus does not alt€r the current beingmeasured. (See page 68.) Problems Sections 3.132 3,1 For each of the circuits shown, a) identify the resistors connected in serieq Figure P3.1 b) simplify the circuit by replacing ttre seriesconnected resiston with equivalent resistors. 3ko 8ko 5ko 4 0 0 4 5 0 soo :ov( ) 3oo 60f) 10v 240 {l 1800 300 () 140 0 200 ()...
