8.3: Initial and Steady-State Analysis of RC Circuits
In reality, practical capacitors can be thought of as an ideal capacitance in parallel with a very large (leakage) resistance, so there will be a limit to this performance. Example 8.3.1 Given the circuit of Figure 8.3.4, find the voltage across the 6 k(Omega) resistor for both the initial and steady-state conditions assuming the capacitor is initially uncharged.

6.1.2: Capacitance and Capacitors
Capacitors are available in a wide range of capacitance values, from just a few picofarads to well in excess of a farad, a range of over 10(^{12}). Unlike resistors, whose physical size relates to their power rating and not their resistance value, the physical size of a capacitor is related to both its capacitance and its voltage rating (a consequence of Equation …
