What are the behaviors of capacitors and inductors at time t=0?
For an uncharged capacitor connected to ground the other pin (the side of the switch) is also at ground potential. At the instant you close the switch the current goes to ground, that''s what it sees. And the current is the same as when you would connect to ground without the capacitor: a short-circuit is a short-circuit.

6 FAQs about [Closed circuit example with capacitor]
What happens when a capacitor is closed?
When switch S is closed, the capacitor is connected directly to the power supply. As there is virtually no resistance in the current path, the capacitor charges up almost instantly to the supply voltage. When S is opened, the capacitor is charged up to V 0, the full supply voltage. Resistor R, connected in parallel, experiences the same voltage.
Can a capacitor be discharged without a voltage source?
To discharge a capacitor, it will need to be placed in a closed circuit without a voltage source. Most of the time a wire is used to connect the two ends of a capacitor for rapid discharging. However, that is dangerous and caution should be used when discharging a capacitor. RC or resistor -capacitor circuits are a basic type of circuit.
What happens when a capacitor is included in a circuit?
When a capacitor is included in a circuit, the current will change with time, as the capacitor charges or discharges. The circuit shown in Figure 20.5.1 20.5. 1 shows an ideal battery 1 (ΔV Δ V), in series with a resistor (R R), a capacitor (C C, two vertical bars) and a switch (S S) that is open.
What happens if you connect capacitors in series?
In a circuit, when you connect capacitors in series as shown in the above image, the total capacitance is decreased. The current through capacitors in series is equal (i.e. i T = i 1 = i 2 = i 3= i n).
Why does a series capacitor have a Q?
This occurs due to the conservation of charge in the circuit. When a charge Q in a series circuit is removed from a plate of the first capacitor (which we denote as − Q), it must be placed on a plate of the second capacitor (which we denote as + Q), and so on.
Which circuit is used to investigate the discharge behaviour of a capacitor?
The circuit opposite can be used to investigate the discharge behaviour of a capacitor. When switch S is closed, the capacitor is connected directly to the power supply. As there is virtually no resistance in the current path, the capacitor charges up almost instantly to the supply voltage.
