### The circuit below is made up of five ideal passive components and a s.pdf

1. The circuit below is made up of five ideal passive components and a sinusoidal voltage source (no DC offset) running at a fixed frequency of w/(2n) Hz. Find the following Rae equivalent c dal be voltage source re by a n betwen will be a fr on of terms of o, L1, L2 points two complex numbers ENDress the numerat nominator somplete expa that enth 2. The equivalent voltage source replaced by an open) between c pedance DG rrana B for very high frequency (w oo). valent circuit im the oltage source replace y an open between s A and Bio quency 0) 4. With the voltage source restored to the circuit, find the value(s) of where the average current in the resistor is zero. L1 C1 VAC T C2 L2 Solution the given circuit is in the form of a wheat stone bridge. for average current through the resistor to be zero, it should be balanced. i.e ZL1 / Zc1 = Zc2 / ZL2 jwL1 / (1/jwc1) = (1/jwc2) / jwL2 -w2 L1 c1 = -1 / w2 L2 c2 w4 = 1/ L1 c1 L2 c2
