The circuit shown below has reached steady state at t = 0-. If the make-before-break switch moves to position b at t = 0, calculate i(t) for t > 0.

For the circuit in Figure 3 the switch is in the left position for several minutes: (a) Find the Initlal voltage, o on the capacitor just before the switch is flipped (b) Find an expression v(t) that describes the voltage across the 20 N resistor after the switch has been Figure 3 1Ω 60 N flipped to the right NOTE: Remember what we said in class: use a Circuit-Specific Equation to get a value you know. Then solve for whatever else the problem asks for O 12 V 5 2 -50 μF 80 Ω 20Ω

After being closed for a long time the switch in the RC circuit shown below opens at timet=18 ms. Find iO(t) for t > 0 ms. For full credit include the equations and a plot describing iO(t).Hint: use superposition to find the contributions of each source.

Switch 1 in the circuit below has been in position A for a very long time. At time t=0, the switch moves to position B. Calculate VC(t) for t>0. Perform your analysis inthe time domain.
