A: PARASITIC means like a parasite is there to offset the actual circuitry it can be inductance and/or capacitance A capacitor is usually wound in a coil this coil if frequency is hi enough will behave as a small coil has been added to the circuit. Hi frequency PWM capacitors have indeed four lead to reduce not eliminate this inductance

What is inductance and capacitance and impedence?
The inductance of an inductor is the capacity of the inductor to induce electric flux. The capacitance of a capacitor is the capacity of the capacitor to store charges. THE IMPEDANCE OF A CIRCUIT IS THE TOTAL OPPOSITION OFFERED TO THE FLOW OF ELECTRIC CURRENT.
What is the use of mylar capacitor?
myler film /myler capacitor is specially designed for low inductance and low resistance,so it has an prpoperty of fast discharging energy
How component size decreases when frequency decreases?
The impedance of a component (inductor or capacitor) will change with frequency - resistor impedances will not. Inductor impedance - j*w*L Capacitor impedance - 1/(j*w*C) L = inductance, C = capacitance, j = i = imaginary number, w = frequency in radians The actual inductance and capacitance does not change with frequency, only the impedance.
How do you measure inductance?
You can use a LCR (Inductance, Capacitance, Resistance) meter if you can find one.
What is the inductance of a circuit containing two 10 mh inductors connected in parallel?
Inductance in parallel is the reciprocal of the sum of the reciprocals of the individual inductance's. LPARALLEL = 1 / SummationI=1toN (1 / LI)
What does a disc capacitor do?
A disc capacitor does exactly the same thing that any other capacitor does, with one difference: it has the lowest value of parasitic inductance of any type of capacitor. As inductance is exactly the opposite property to capacitance, its presence in a capacitor is very undesirable in many applications and can sometimes result in circuit instability.
Should you worry about capacitor lead length in a circuit?
Capacitor lead length is a consideration in a circuit when the frequency involved is sufficient the make the parasitic capacitance and inductance of the leads important.
What is the name of the device used for measuring the inductance of a capacitor?
A capacitor nominally has no inductance, which is lucky because there is no such device to mesure it with.
Does capacitance exist for a resistor?
yes, parasitic. there is also parasitic inductance.
Why the laser diode has internal capacitance?
All real components have both parasitic capacitance and parasitic inductance.
Uses of gang capacitor?
Gang capacitors are commonly used in radio tuners/receivers. Radio tuners/receivers have formation of LC(inductance and capacitor). Here this circuit has one fixed inductance and capacitor parallel with gang capacitor. Normally gang capacitor used in superhetrodyne receiver.
What is a pure capacitor?
whose resistance=0,inductance=0
What are the different ways a Capacitor can be used in circuits?
There are several types of capacitors (mainly depending on dielectric: electrolytic, coiled paper, air, ceramic) and for different purposes, the main idea for them is to allow current path for high frequency but a capacitor does not have only capacitance, it does have certain amount of series resistance and inductance depending on design so what works fine in audio frequencies do not do same job for radio frequencies or microwaves as the parasitic inductance becomes relevant. Some other use is tunning or preset where the capacitance is adjustable in order to accomplish resonance with an inductance. A capacitor (series of) is used in a ladder with diodes to rise DC from a low voltage oscillator. Killing HF oscillation is another use avoiding parasitic feedbacks.
What is parasitic capacitor?
It constantly "drains" the circuit
What is inductance and capacitance and impedence?
The inductance of an inductor is the capacity of the inductor to induce electric flux. The capacitance of a capacitor is the capacity of the capacitor to store charges. THE IMPEDANCE OF A CIRCUIT IS THE TOTAL OPPOSITION OFFERED TO THE FLOW OF ELECTRIC CURRENT.
What is the functions of ceramic capacitor?
Ceramic capacitors can be used anywhere a capacitor having very low internal parasitic inductance is required. Most commonly they are used as powersupply bypass capacitors. They are also sometimes used for coupling capacitors for HF signal amplifiers.
What is the use of mylar capacitor?
myler film /myler capacitor is specially designed for low inductance and low resistance,so it has an prpoperty of fast discharging energy
