Resistors in Parallel. In the previous section, we learned that resistors in series are resistors that are connected one after the other. If we instead combine resistors by connecting them next to each other, as shown in Figure 19.16, then the resistors are said to be connected in parallel.Resistors are in parallel when both ends of each resistor are connected directly …
Circuit short circuit capacitor question confusion
After, with the switch closed, the current source and 200 $Omega $ resistor are paralleled with a short circuit and so, from the perspective of the capacitor, can be ignored (a short circuit in parallel with any other circuit elements is equivalent to a short circuit).
Why does a capacitor act like a short-circuit during a current …
$begingroup$ @user29568, a capacitor acts as short circuit in two different limits: (1) as an AC short circuit as the frequency goes to infinity and (2) as an actual short circuit (assuming the capacitor is uncharged) as C goes to infinity.
Inductor and Capacitor in Parallel
A capacitor will look like an open circuit. Inductor will look like a short circuit. Alfred Centauri has shown you the equations for the basis of these rules. So, when you say,"…the capacitor will charge up to 10V almost instantaneously" is incorrect.

6.1.2: Capacitance and Capacitors
Capacitors in Series and in Parallel. Multiple capacitors placed in series and/or parallel do not behave in the same manner as resistors.

The expression in Equation ref{8.10} for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors. To see this, consider any uncharged capacitor (not necessarily a parallel-plate type). At some instant, we connect it across a battery, giving it a potential difference (V = q/C) between its plates.

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?

capacitor
The capacitor goes to natural response when the gate shuts. $ v (t) = Ve^{t/tau}$ where $ tau= R_{eq}C $ Since there is no current flowing at parallel resistor due to short circuit, we can basically delete it or just make it shorted. And as seen by the capacitor, with parallel resistor shorted too, shouldn''t
