What happens if we replace capacitor with inductor?
At some point, the change in potential across the inductor will be greater than that across the capacitor (since the capacitor loses charge with current flow) and then the current will reverse directions and charge the capacitor back up. The process repeats itself—forever since there is no resistance.
What will be the effect when both an inductor and a capacitor are connected to the circuit?
If an inductor is connected across a charged capacitor, the voltage across the capacitor will drive a current through the inductor, building up a magnetic field around it. The voltage across the capacitor falls to zero as the charge is used up by the current flow.
Can we use a capacitor in place of inductor to control AC current explain?
Likewise, an inductor in series is similar to a capacitor in parallel, but again, the loading effect is not the same. We can use a capacitor to prevent AC, or AC above certain frequencies, from entering a circuit, by shunting those signals to the return.
How does an inductor and capacitor combine in parallel?
As the capacitor charges and the inductor builds it’s field, toward a peak, the capacitor and inductor combine to go a resonant circuit with the equivalent circuit of the capacitor, inductor and resistor all in parallel (assuming infinitesimal impedance at the battery).
What happens to the inductor when the switch is closed?
Now when the switch is closed for a long time inductor is now a short-circuit with 0.2 A flowing in it and the resistor, and there is no voltage across the capacitor. So your book is correct about the current in the inductor and wrong about the voltage across the capacitor. Hope this helps.
Can a capacitor be replaced with an inductor?
and so, since the inductor current is constant, the voltage across the inductor is zero. This is why you can replace the inductor with a wire. and so, since the capacitor voltage is constant, the current through the capacitor is zero. This why you can replace the capacitor with an open-circuit.
What happens in the discharging of a capacitor through inductor?
Thus in discharging process of a capacitor through inductor, there is an oscillation of energy/voltage/charge from capacitor to inductor and inductor to capacitor. According to KVL, the algebraic sum of instantaneous voltage drop across the circuit elements for a closed loop is zero.
