What is the current through the inductor when the capacitor is fully discharged?
A fully discharged inductor (no magnetic field), having zero current through it, will initially act as an open-circuit when attached to a source of voltage (as it tries to maintain zero current), dropping maximum voltage across its leads.
When a charged capacitor is made to discharge through an inductor?
When a charged capacitor is made to discharge through an inductor, the charge Q on the capacitor and the current i in the inductor vary sinusoidally, The phase difference between Q and i is 1) Tt 2) 1/2 3) 1/4 4) zero purce Itage.
When a charged capacitor is allowed to discharge?
A charged capacitor is allowed to discharge through a resistor by closing the key at the instant t=0 (see Figure). At the instant t=(ln4)μs, the reading of the ammeter falls half the initial value.
What is the necessary condition to discharge a capacitor?
A Capacitor is a passive device that stores energy in its Electric Field and returns energy to the circuit whenever required. When the Capacitor disconnected from the Power Supply, the Capacitor is discharging through the Resistor RD and the Voltage between the Plates drops down gradually to zero, vc = 0, Figure 4.
Is it possible to charge an inductor the same way as a capacitor?
I wanted to know if it’s practically possible to use inductors the same way we use capacitors , in the sense of charging it using a charging circuit then discharge in another circuit.
When does an inductor start to charge and discharge?
Inductor charge for half-cycle up to the peak voltage. When the first cycle ends the inductor start to discharge first.
Do you need a resistor to discharge a capacitor?
In fact, it is not necessary actually to have a physical resistor in the circuit. Even if the capacitor and inductor were connected by superconducting wires of zero resistance, while the charge in the circuit is slopping around between the capacitor and the inductor, it will be radiating electromagnetic energy into space and hence losing energy.
How is energy stored when a capacitor is discharged?
How is it possible that when the capacitor is fully discharged, when the current is zero to have the entire energy to be stored in the induction, when the current is zero, there is no magnetic field and the how can the inductor store energy in that case. There is still a magnetic field when the capacitor reaches zero charge.
