What is the mutual capacitance of two spheres?
The capacitance of two spheres can be calculated using the 'method of images' repeatedly. This gives the result as a fast converging series. Details: http://www.iue.tuwien.ac.at/phd/wasshuber/node77.html
Two spheres have equal densities and are subject only to their mutual gravitational attraction. Which quantity must have the same magnitude for both spheres?
To increase the capitance of a capacitor you can add another one in parallel with it. In other words, connect another capacitors negative lead to the negative lead and the positive lead to the positive lead of the existing capacitor to increase capacitance. Connecting in series will reduce capacitance. Two capacitors of the same value in parallel will double capacitance, two in series of the same value will halve the capacitance.
Diffusion capacitance is the capacitance due to transport of charge carriers between two terminals of a device. - Amog This diffusion capacitance is due to depletion capacitance which is a function of forward bias applied to emitter junction of a transistor and due to diffusion capacitance which a function of transconductance of the transistor. Its value is 100 pF. Tirupanyam B.V
What is the formula for calculating self capacitance of an inductor when the value of capacitance and frequency for two capacitors is given?
You seem to be mixing up your terminology. There is no such thing as 'self-capacitance of an inductor'! If you know the frequency and equivalent capacitance for two capacitors, then you can find the equivalent capacitive reactance of the capacitors, but that's not what you seem to be asking! I suggest you rephrase the question.
The job of a capacitor is to store charge onto its plates. The amount of electrical charge that a capacitor can store on its plates is known as its Capacitance value and depends upon three main factors. The surface area, A of the two conductive plates which make up the capacitor, the larger the area the greater the capacitance. The distance, d between the two plates, the smaller the distance the greater the capacitance. The…
Not sure what you are asking. There are two formulae for working out equivalent capacitance: Two capacitors in parallel The equivalent single capacitance is the sum of the two capacitors: Ce = C1 + C2 Two capacitors in series The equivalent single capacitance is the reciprocal of the sum of the reciprocals of the two capacitors: 1/Ce = 1/C1 + 1/C2 ⇒ Ce = C1C2/(C1+C2) So you can replace two capacitors by a single one…
Capacitance in mosfet is of three types: gate capacitance diffusion capacitance routing capacitance Gate capacitance: limits the speed of the device t which it can be operated Diffusion capacitance: It is the capacitance due to charge carriers between drain and source. Routing capacitance: It is the capacitance of the metal which is deposited on the top of oxide layer.
There are two 5.0 g spheres each suspended from 1.0 m long threads The spheres repel each other after being charged to 91nC What is the angle theta?
An example of an induction charging of two metal spheres. The metal spheres are supported by insulating stands so that any charge acquired by the spheres cannot travel to the ground. The spheres are placed side by side (see diagram i. below) so as to form a two-sphere system. Being made of metal (a conductor), electrons are free to move between the spheres - from sphere A to sphere B and vice versa.
Two similar capacitors are first connected in parallel and then in series what is the ratio in the two cases?
Any two adjacent conductors can be considered a capacitor, although the capacitance will be small unless the conductors are close together for long. This (often unwanted) effect is termed "stray capacitance". Stray capacitance can allow signals to leak between otherwise isolated circuits (an effect called crosstalk), and it can be a limiting factor for proper functioning of circuits at high frequency. Stray capacitance is often encountered in amplifier circuits in the form of "feedthrough" capacitance…
Parasitic capacitance is unavoidable and usually unwanted capacity between two or more conductors which exists due to close proximity and which typically causes non-ideal circuit behavior. Stray capacitance, as it is typically thought of, is a type of parasitic capacitance. It is the capacity from a conductor to its surroundings which is the aggregate of the conductors in its environment inversely weighted by the distance to each of the environmental conductors.
Two spheres Earth have are the atmosphere and the biosphere. The Earth also have the lithospher and the hydrospher. All four spheres contain a purpose to the Earth. Atmospher: all of the oxygen and other gasses Biosphere: all of the life on earth Lithosphere: all of the plate tectonics Hydrosphere: all of the water on Earth
We represent the particles (atoms) in magnesium metal as spheres stacked closely together. Magnesium burns when these particles react with the oxygen particles in the surrounding air. The oxygen particles are represented as molecules consisting of two oxygen atoms bonded together. We represent this as two spheres pressed together. The product of the reaction is magnesium oxide and we represent this by joining one of the oxygen spheres to one of the magnesium spheres.
