What is the symbol for an inductor?
The inductor symbol resembles a coil of wire of 3 to 5 turns.
Why voltage leads current in a inductor?
Eli the ice man. Voltage (E) before Current (I) in a coil (inductor)(L) Current (I) before Voltage (E) in a Cap. (C) Got it?
Why a coil of wire placaed in series circuit allows low frequency current but not high frequency current to pass?
The opposition to an alternating current offered by a coil, or inductor, is called impedance (symbol Z, measured in ohms) which, in turn, is made up of two components: resistance (symbol R) and inductive reactance (symbol XL). These three quantities are related as follows: Z2 = R2 + XL2.The resistance of an inductor is a fixed value which depends upon the length of the coil's wire, the cross-sectional area of the wire, and the resistivity of the material from which the wire is made.The inductive reactance of an inductor, on the other hand is directly proportional to the frequency of the supply. So, at high frequencies, an inductor's inductive reactance is very much higher than at low frequencies.So, at high frequencies, the impedance of the inductor is higher because its inductive reactance is higher.The current flowing through a coil is, by Ohm's Law: I = V / Z. So, at high frequencies, the inductor's impedance will be much higher than at low frequencies, which means that a very much smaller current will flow when the frequency is high compare to when the frequency is low.
The only device that develops true power in an electronic circuit is the inductor?
The resistor is the only component to develop true power in an ac circuit. The inductor and capacitors absorb energy on one half cycle and return it to the supply on the next. The resistive part of the inductor (wire coil if low frequency type) will develop true power due to its value of resistance ie it will get warm.
How does an inductor work?
Basically, an inductor is a coil of wire. The core of the inductor, the material it is would around, could be air, ferromagnetic material, or something else. The windings of the coil are usually copper wire, and they are coated with some kind of insulator, often enamel. It has two terminals, one at each end of the coil. Let's hook it up and see what happens.When we apply a voltage to the coil, current will want to move through the windings. But the instant that current wants to start moving, that current will want to form a magnetic field around its path of travel. This is a fundamental concept as regards moving charges; they always form a magnetic field around their path of travel.As the magnetic field begins to form, it will start to expand around the wire. As the field expands around one wire, that field will expand "across" other windings. Each winding will have an expanding magnetic field that "sweeps" or expands across all the other windings. As the expanding magnetic field around each wire sweeps all the other windings, it induces a voltage in those windings that opposes the voltage applied to the coil. The action of the opposing magnetic field wants to stop or prevent current flow. This is at the heart of how an inductor works, and this is the principle of induction in action. Let's follow through and tighten things up.As the field expands and generates (induces) that opposite voltage, the inductive action will limit the ability of the windings to conduct current flow. Eventually the current will flow, but only after a bit of time. There is a "delay" between the application of voltage to an inductor and that inductor's ability to pass current through itself. This is why we say that current lags voltagein an inductor. The current only flows "later" after the voltage rises and peaks. The delay spoken of here is only very brief, but when we apply AC to an inductor (pure inductance), the current will lag the applied voltage by 90 degrees.When voltage across an inductor peaks and falls off, the magnetic field that had built up will collapse. As this field collapses, it will again be sweeping all the windings in the coil, and will induce a voltage that wants to keep current flowing the way it was flowing already. The inductor is "resisting" a change in the current flow through it. And this is a fundamental characteristic of an inductor.And inductor is a device that resists a change in current flow throught it. And current flow through an inductor will lag the applied voltage by 90 degrees in AC circuits, provided there is no resistance in the circuit. This is boilerplate electronics, and the electronics student will see this information in some form on a test.
What is meant by inductor and name the inductor device?
a coil. a component having the property of inductance.
What is the symbol for an inductor?
The inductor symbol resembles a coil of wire of 3 to 5 turns.
Working of a capitance and coil?
A ferrite core inductor with two 47 mH windings. An inductor usually consists of a coil of conducting material.
What is the difference between coil inductor solenoid?
Physicall no difference.But inductor uses ac and solinoid uses dc.
In which place an inductor store energy in it?
Because inductor forms a coil with magnetic field around it. It acts as a relay also. Tasleem
What is the reactance value when inductor was saturate?
A: when a coil is saturated there is only resistance of copper
Why doesnt a field coil in a DC shunt motor lead to short ciruit when it is a fact that an INDUCTOR is a short circuit to DC?
Yes, an inductor is a short circuit to dc...that's true....IF the inductor is an ideal one, that is, the inductor has no resistance but has inductance only. Anything in real world, as you know, is not ideal. An inductor is usually made of a copper wire. A copper wire has its own resistance. If an inductor coil is thin and long (i.e. many turns), it will provide an appreciable resistance to DC, and will no longer be a short circuit.
What is the swirly line in a circuit diagram?
Could be an inductor / coil, without metal core.
Contains both resistance and inductance?
Wire. conductors. Wire made into a coil, an inductor.
What is Tapped Inductor?
A tapped inductor is a coil to which electrical access is available at more points than only the two ends. Connection points are provided at one or more points on the coil that are between the ends. Each such point is called a 'tap'.
What is another name for an inductor?
Once referred to as a coil; still sometimes mis-called an inductance.
What device works by rotating a wire coil within a magnetic field to produce current?
inductor
