Short circuit of parallel capacitors
With R 3 shorted there is a short circuit in parallel with R 2. The short circuit routes the current around R 2, effectively removing R 2 from the circuit. Total circuit resistance is now equal to the resistance of R 1, or 20 ohms. As you know, R 2 and R 3 form a parallel network. Resistance of the network can be calculated as follows: - Download [PDF]

Does connecting a capacitor in parallel with a wire "short" it out?
I have a question about capacitors. In the circuit below, capacitor C2 is in parallel with a wire. When a resistor is connected in parallel to a wire, the potential across it equals zero so no current goes through it. My questions are does the potential difference across C2 equal zero because it''s in parallel with a wire?

(b) Q = C eq V. Substituting the values, we get. Q = 2 μF × 18 V = 36 μ C. V 1 = Q/C 1 = 36 μ C/ 6 μ F = 6 V. V 2 = Q/C 2 = 36 μ C/ 3 μ F = 12 V (c) When capacitors are connected in series, the magnitude of charge Q on each capacitor is the same.The charge on each capacitor will equal the charge supplied by the battery. Thus, each capacitor will have a charge of 36 μC.

In our ideal capacitor model, an uncharged capacitor is assumed to contain nothing that would slow down the flow of current. The device has an instantaneous resistance of zero, corresponding to a short circuit at that particular time (which is also a reasonable approximation for adjacent time points much less than the charging time constant of the circuit).

Capacitors
After popping an electrolytic will behave like a short circuit. These caps also notorious for leakage-- allowing small amounts of current (on the order of nA) to run through the dielectric from one terminal to the other. This makes electrolytic caps less-than-ideal for energy storage, which is unfortunate given their high capacity and voltage ...
Capacitor Transient Response
A fully discharged capacitor, having a terminal voltage of zero, will initially act as a short-circuit when attached to a source of voltage, drawing maximum current as it begins to build a charge. Over time, the capacitor''s terminal voltage rises to meet the applied voltage from the source, and the current through the capacitor decreases ...
What are the behaviors of capacitors and inductors at time t=0?
An inductor is a wire. After it saturates the core, it behaves like a short circuit. A capacitor is a gap between two conductors. After it charges, it behaves like an open circuit. Their instantaneous behavior is the opposite. Until they charge, a cap acts like a short circuit, and an inductor acts like an open circuit.
