kar Name 4ll/200911:05:00 AM 1. The following circuit is from Lab 11. If the input phasor voltage Vl is 5/.0'V find the phasor voltage V3 across the inductor and the phasor voltage Yc =Y2-V3 across the capacitor at a frequency of 50.329 WIz. Plot this phasor diagram. What is the phasor voltage V2 across both the capacitor and inductor? - i ')-- '- 2'- Air *. tr'ffi,1o'./D,to'1 O = - j7/4-22'f )L'L = izn(L -, = i7n 5t>tz1 ^/"lD , i"3/l.zL I t3/(,. z= j t9. st Vz 2 tb' ///b * JO:J 29 3/ / -?+) V3 ^1 T I Vc= 5k' V*-' /s.sl Class Homework Problerns #19 Monday, Apr.6,2009 o Vt' /5.stlZ -;7il,2> : -: /t,7/ /rzu + 1 /9t t'?>- 7/ 6 z\) V= V,, *Vt, j/!-,xt-i)t'71 =

In the circuit shown below find the voltage v6(f) across the resistor. Note that in this circuit the two voltage sources have different frequencies. This means that you rza^rt use superposition to solve this problem. We can't use mesh analysis, for example, because the impedances of the inductor and capacitor will be different for the two different voltege sources.
