Consider the RC circuit shown in the figure below, in which the
capacitor is initially charged.
The graph above shows the voltage at the capacitor terminals,
resulting from switch closure at t = 0s (the exponential curve).
The capacitor is 1 microF and the source voltage is 5V. Noting the
exponential curve that corresponds to the output level yo (t)
measured in capacitor terminals, estimate the order of magnitude of
resistor R and justify your answer. Find the complete response...

The various devices in which RC and RL circuits find applications and some of these applications take advantage of the short or long time constants of RC or RL circuits. The Following circuit shown in Figure 9 is used by a biology student to study "frog kick." She noticed that the frog kicked a little when the switch was closed but kicked violently for 5s when the switch was opened. (i) Model the frog as a resistor and calculate its...

1. The difference equation for a single stage RC circuit, when the input is 1v., is shown below (see Lab 4): y(n) = (y(n-1) + a * Ts) / (1 + a * Ts) (0 < t < 1) where a = 1 / (RC) Ignore the difference equation for the case t > 1, when the input is 0v. (a) Find the Z-transform of y(n) analytically, assuming a time constant of a = 5 and sampling interval of Ts...
