6 FAQs about [Capacitor discharges through the self-inductance coil]
What happens if a capacitor is connected to an inductor?
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. The effect is just as if a resistance were in the circuit.
What happens when a capacitor is closed?
The switch is closed, and charge flows out of the capacitor and hence a current flows through the inductor. Thus while the electric field in the capacitor diminishes, the magnetic field in the inductor grows, and a back electromotive force (EMF) is induced in the inductor. Let Q Q be the charge in the capacitor at some time.
How does a primary coil work?
The primary coil contains seven turns of wire arranged into a large inductor which has about 0.01mH inductance. It is connected to a capacitor back via a spark gap. The capacitor bank has capacitance 0.03uF and is rated to a peak voltage of 20kV. The capacitor is charged directly from a 12kV transformer capable of delivering up to 50mA of current.
How does a capacitor work in a differential equation?
Those with no experience in differential equations will have to take the solutions given on trust. A charged capacitor of capacitance C C is connected in series with a switch and an inductor of inductance L L. The switch is closed, and charge flows out of the capacitor and hence a current flows through the inductor.
How does a coil former affect the self-capacitance of a wire?
Approximately can be considered that the presence of the coil-former increases the self-capacitance compared with an estimated up to 15..30%, former with grooves under the wire increases the capacitance up to 40%, the impregnation and enveloping coils with varnish or compound increases the self-capacitance of up to 50% and above.
Who invented the self-capacitance of coil inductance?
The first time the question of self-capacitance of the coil inductance was raised by J.C. Hubbard in 1917. S.Butterworth, all known innovator and designer of frequency filtering circuits (remember Butterworth filters) in 1926 proposed a formula for the calculation, but it had serious limitations and could not count short coil.
