What is the letter symbol for the Inductor?

What happens when dc supply is given to inductor?
The resulting maximum current is limited by the resistance of the inductor. As the current increases from zero to that maximum value, its expanding magnetic field induces a voltage into the inductor which opposes the rise in that current. So, instead of reaching its maximum value instantaneously, it takes some time -determined by the equation:time to maximum current = 5 L / R (seconds)where L = inductance of inductor in henrys, and R = resistance of inductor in ohms.
What is the reactance of a 3-H inductor when the frequency is 100Hz?
The reactance (X_L) of an inductor is calculated using the formula (X_L = 2\pi f L), where (f) is the frequency in hertz and (L) is the inductance in henries. For a 3-H inductor at a frequency of 100 Hz, the reactance is (X_L = 2\pi (100)(3) \approx 1884.96 , \Omega). Thus, the reactance of the 3-H inductor at 100 Hz is approximately 1885 ohms.
What is the time constant of a 20 mH inductor in series with a 230 W resistor?

What is the inductive reactance to 1Hz in a 1H inductor?
Inductive reactance (X_L) is calculated using the formula (X_L = 2\pi f L), where (f) is the frequency in hertz and (L) is the inductance in henries. For a 1H inductor at 1Hz, (X_L = 2\pi(1)(1) = 2\pi \approx 6.28 , \Omega). Therefore, the inductive reactance to 1Hz in a 1H inductor is approximately 6.28 ohms.
What is the letter symbol for the Inductor?
letter symbol is L
What is the symbol for inductor?
L is the symbol for inductance. An inductor is a passive two-terminal electrical component which resists changes in electric current passing through it.
What is the symbol for an inductor?
The inductor symbol resembles a coil of wire of 3 to 5 turns.
How do you increase the inductance in a inductor?
Since we know that inductance of an inductor depends on the length of inductor by the formula L=muAN*N/l, where l is the length of inductor. So by varying the length of inductor we say that inductance of inductor varies.
Why inductor is denoted as L?
The term 'inductance' was coined by Oliver Heaviside in February 1886.[1] It is customary to use the symbol L for inductance, possibly in honour of the physicist Heinrich Lenz.
Is a inductor linear device?
Inductor is a nonlinear device. since v=L di/dt.
How do you calculate the number of windings in a capacitor given the length?
You surely do mean inductor, not capacitor. The length is not enough to determine the number of windings for an inductor. Inductance is bound with following parameters by equation: L = (pi/4) * mi * (N * d)^2 / l, where: L - inductance mi - permeability of inductor core N - number of windings d - diameter of inductor l - length of inductor Using those data, you can transform the equation to: N = sqrt(2*L*l/(mi*pi))/d
Why does the inductance of inductor varies with frequency?
It doesn't. the impedance of the inductor will, following the rule j*w*l, where l is inductance, w is frequency in radians and j is the imaginary number designating this a reactance, not resistance.
What happens when dc supply is given to inductor?

Does inductor allow ac to pass through it?
Yes, with some difficulty. You can think of an inductor as a kind of "AC resistor"in a way. The higher the frequency of the AC, the more difficulty it has passingthrough the inductor.If you apply AC voltage across an inductor, whereV = voltage of the ACf = frequency of the ACL = inductance of the inductor,then the AC current through the inductor isI = V/2 pi f L
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 reactance of a 3-H inductor when the frequency is 100Hz?
