EE 201: Electric Circuits c) IfR is larger than the value calculated in a), the circuit will be in (Circle the correct answer): (3 pts): A. Under-damped condition; B. Over-damped condition; C. Critical-damped condition. d) If R is larger than the value calculated in a), (Circle the correct answer) (2 pts): A. Ringing will happen; B. The response will still be smooth but will settle slower, without ringing. D. The response will still be smooth but will settle faster, without ringing.
Problem 4: RLC circuits (20 pts) 102 w t=0 + 100mV DC Li_(t) lic(t) Lir(t) R v(t) 1μΗ 1 uF The initial energy stored in the inductor and capacitor is zero. At t=0, a 100mV DC source is attached to the RLC circuit through a 192 resistor. We know the equation and parameters for t20+ at critical damped condition: dv(0+) v(t) = D te-at + Dze-at; v(0+) = D2, = D1 - aDz; dt and for parallel RLC circuit, a = 2RC = VEC a) Find the R value for critical damping (6 pts) (hint: you may convert the 100mV DC and 10 to current-source-based equivalent circuit first using source transformation) b) What will be initial current of il(0), ic(0*) and ir(0*).
