2-1 Vottag€ and Cunent Sourc€s 25 The circuit symbols Ior the ideal dependent sources are shown in Fig. 2.2. A diamond is used to represent a dependert source. Both the depeDdent current source and the dependent voltage source may be con- trolled by either a voltage ot a current elsewhere in the circuit, so there are a total of four variations, as indicated by the symbols in Fig. 2.2. Dependent sourcesare sometimes called controlled sources. To completely specify an ideal dependent voltage-controlled voltage source! you must identify the controlling voltage, the equationthat per- mits you to compute the supplied voltage ftom the controlling voltage, and the reference poladty for the supplied voltage.ln Fig.2.2(a),tlre con- trollirg voltage is named o,, the equation that determines the supplied I, = Itrx. and the reference polarity for ?r is as indicated. Note that ri is a multiply- ing constant that is dimensionless.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
