How does current flow in a circuit with a capacitor?
$begingroup$ Correct me if I am wrong, but how does the capacitor pass current when it is in series with an AC signal source? The current "passes" but not in the way that you expect. Since the voltage changes sinusoidally, the voltages also changes across the capacitor, which gives rise to an EMF that induces a current on the other side of the capacitor.
6 FAQs about [What to do with an uncharged capacitor]
What happens if a capacitor is uncharged?
The resulting total charge remains zero. When we say that a capacitor is uncharged it means that the net charge on each plate of the capacitor is zero ie equal numbers of positively charged ions and negatively charged electrons.
What happens if you charge a capacitor using a DC supply?
If I charge a capacitor using a DC supply, the capacitor will gain charge Q0 Q 0. Now, if I discharged it along an uncharged capacitor in this arrangement, according to the lecture notes, the capacitors share the total charge Q0 Q 0. Now, I had a question.
Are there electrons on the uncharged capacitor?
Aren't there electrons on the uncharged capacitor, such that they flow between the two capacitors to cause equal p.d. on both capacitors hence the total charge in this circuit greater than Q0 Q 0? No. Charge must be conserved.
What does charging a capacitor mean?
Capacitor Charging Definition: Charging a capacitor means connecting it to a voltage source, causing its voltage to rise until it matches the source voltage. Initial Current: When first connected, the current is determined by the source voltage and the resistor (V/R).
What happens when a capacitor is charged?
When we charge a capacitor, it gains charge q on one of the plates and loses charge q from the other plate, i.e., its total charge remains zero. Capacitors differ, in that sense, from other objects, like our bodies or spheres and rods used in various electrostatic devices and experiments, which actually gain a net charge, when they are charged.
Why does a capacitor not change when charged or discharged?
When a capacitor is either charged or discharged through resistance, it requires a specific amount of time to get fully charged or fully discharged. That’s the reason, voltages found across a capacitor do not change immediately (because charge requires a specific time for movement from one point to another point).
