Define capacitance with respect to physical structure and electrical function?
capacitance, in electricity, capability of a body, system, circuit, or device for storing electric charge. Capacitance is expressed as the ratio of stored charge in coulombs to the impressed potential difference in volts. The resulting unit of capacitance is the farad [for Michael Faraday]. In an electric circuit the device designed to store charge is called a capacitor. An ideal capacitor, i.e., one having no resistance or inductance, may be spoken of as a capacitance. When an alternating current flows through a capacitor, the capacitor produces a reactance that resists the current (see impedance). While every element of a circuit has some capacitance, it is a goal of good design to reduce such unwanted or stray capacitance to a minimum.
What happens to a capacitance if the volume is filled with material having a dielectric constant of 5?
The capacitance will increase. When the volume is filled with a material with a dielectric constant greater than 1, the capacitance of the capacitor increases by a factor equal to the material's dielectric constant. This is because the electric field is effectively reduced within the material, allowing more charge to be stored for the same voltage.
What is the effect of inserting a dielectric other than air vacuum between the plates of a capacitor?
Inserting a dielectric other than air or vacuum between the plates of a capacitor increases the capacitance of the capacitor. The dielectric material increases the electric field strength within the capacitor, which enhances its ability to store charge. This results in a higher capacitance value compared to having air or vacuum between the plates.
What do you mean by fixed capacitor?
A capacitor having a definite capacitance value that cannot be adjusted. Viper1
What is dynamic impedance?
The impedance of a circuit having an inductance and a capacitance in parallel at the frequency at which this impedance has a maximum value. Also known as rejector impedance.
When ions having a positive charge form Bond with ions having a negative charge the charge on the resulting compounds is?
false
A parallel plate capacitor with each plate having area of 1m2 and you separate the plates by 2 µm what is the value of the capacitance how much charge will the capacitor store connected to a 10V batt?
Find capacitance: C = Er * Eo * A / d C = (1.0005898) * (8.854×10−12)* (1meter squared) / 2 x 10^-6 C = 4.42 micro farads To determine charge Q: Q = C*V = 4.42 x 10^-6 * 10 volts = 4.42 x 10^-5 coulumbs.
What is a good wireless charger to charge my iphone without having to charge the wireless charger before I use it I don't want a hand crank wireless iphone charger or anything like that?
Not possible ! You would need to charge the device to transfer power to the iphone ! You cannot get power out of nothing !
Can a parallel plate capacitor of 1 farad capacitance having plate separation of 1 mm be actually constructed in laboratory?
no
Can you get a charge from the police for having a Peace Pipe?
What does the questioner consider to be a "Peace Pipe?" Usually it is not the smoking device itself, it is what is IN the pipe or more often, the residue in the pipe, that is the illegal substance.
When ions having a positive charge form bonds with ions having a negative charge the charge on the resulting compound is what?
The charge is 0 if the positive and negative charges were equal
When ions having a positive charge from bonds with ions having a negative charge the charge on the resultion compound is negative?
just put true
