What else can I help you with?
What is the initial condition of the elements capacitor and inductor that have no initial energy stored?
The initial condition of a capacitor that has no energy stored is zero volts. The initial condition of an inductor that has no energy stored is zero amperes.
What is the unit of energy of inductor?
I am not entirely sure what you mean. Energy is measured in joules. The energy stored in an inductor would therefore also be measured in joules. The "strength" of an inductor is measured in henry, but that is not an energy unit.
What is the difference between an inductor and a capacitor?
Firstly the suffix '-ance' in each of those three words indicate the properties the material exhibits. Therefore resistance is the property by which any material tends to oppose the flow of current through it. Inductance is the property by which a material opposes the change in current, or opposes an alternating current. An inductor can be appreciated simply using a coil of insulated wire, or a solenoid. Capacitance is the property by which a material opposes the change in voltage across its ends, ie how it opposes alternating voltage. A capacitor comprises of, essentially, two metallic plates separated by a dielectric (a medium which may/may not be non-conducting, but is capable to contain charge). cheers!!
What is a simple definition of electrical energy?
The energy in an electrical current, or stored temporarily in capacitors or inductances.
Is Q factor ratio of energy stored to energy dissipated?
yes ,Q factor is ratio of energy stored to energy dissipated
What amount of energy is stored in a 4.7mH inductor when the current is 20mA?
The energy stored in an inductor is given by the formula W = 1/2 * L * I^2, where W is the energy in joules, L is the inductance in henries, and I is the current in amperes. Substituting the values given, we get W = 1/2 * 4.7mH * (20mA)^2 = 4.7mJ. Thus, the energy stored in the inductor is 4.7 millijoules.
During the first quarter cycle energy is given to an inductor. and the same amount of energy is returned by the inductor during the next quarter cycle .then how is energy stored in inductor?
Well, first of all, nobody ever claimed that the energy is stored 'in the inductor'.The energy is stored in the inductor's magnetic field.Next: When they say that energy is stored, it doesn't necessarily mean that it'sstored like in a box or a jar, and you can fill it up, put it up on the shelf, then comeback and get it in a few days.The energy stored in the magnetic field is steady as long as the current through theinductor is steady. If the current is changing, then the energy in the magnetic fieldis also changing. When the energy in the magnetic field is decreasing, then of coursethe magnetic field is returning some of its stored energy to the circuit, by way of thecurrent.
Where is energy stored in a capacitor and in inductor?
Energy is stored in a capacitor in the electric field between its plates. In an inductor, energy is stored in the magnetic field around the coil.
How does an inductor work to store and release energy in an electrical circuit?
An inductor works by storing energy in the form of a magnetic field when current flows through it. When the current changes, the magnetic field also changes, inducing a voltage in the inductor. This stored energy can then be released back into the circuit when needed.
What type of energy stored in inductor?
heat energy
Equaction of energy related to inductor?
Energy stored in the inductance 'L' through which the current 'I' flows is [ 1/2 L I2 ].
What is the initial condition of the elements capacitor and inductor that have no initial energy stored?
The initial condition of a capacitor that has no energy stored is zero volts. The initial condition of an inductor that has no energy stored is zero amperes.
Suppose no energy given to inductor and a decreasing current is applied to it. emf will be produced and energy is given by it.so i think energy is not stored in inductor. it is its own property?
How do you propose to connect a decreasing current to the inductor ? The initial current through the inductor is zero, and you want to connect it to a current which is not zero and decreasing. At the instant you make the connection, the inductor current is zero, and it must rise to the non-zero value where you want it to begin decreasing. The current in the inductor cannot change from zero to something in zero time. As it rises from zero to the initial value, guess what . . . the inductor is storing energy in its magnetic field, while producing the usual voltage equal to [ L di/dt ].
Energy is stored in inductor in magnetic field.magnetic field exists only where the charge is moving.so does the moving charge is stored in an inductor.if not then how is energy stored in inductor?
the energy is stored in the magnetic field surrounding the inductor, which takes time to build up and time to collapse. when current is first applied, the absence of magnetic field opposes it until the field has built up. when current is removed, the built up magnetic field opposes it forcing current to flow until the field has collapsed.nothing happens instantly when dealing with fields, either magnetic or electrostatic.
What is the reason behind the lag of current in inductor lead in capacitor?
The physics of the energy storage. In an inductor, the current must fight against the stored energy in the magnetic field which tries to keep the current unchanged. Any change in the current lags the voltage since the stored energy impacts the adjustment. Similarly, the "displacement" current in a capacitor leads the electric field buildup in a capacitor, causing the voltage to lag the current until the stored energy building up in the electric field stabilizes. Any change in the voltage is first preceded by a change in the displacement current.
What is the unit of energy of inductor?
I am not entirely sure what you mean. Energy is measured in joules. The energy stored in an inductor would therefore also be measured in joules. The "strength" of an inductor is measured in henry, but that is not an energy unit.
Is electric current stored anywhere?
Electric current is the movement of charge around a circuit and so cannot really be stored, however, the energy which it carries is stored in most things.
