How do you find the resistance of an inductive coil?
How do you find the resistance of an inductive coil?
The formula for calculating the inductive reactance of a coil is: inductive reactance, or XL, is the product of 2 times p (pi), or 6.28, the frequency of the ac current, in hertz, and the inductance of the coil, in henries. XL =2p x f x L. L = the inductance value of the coil in henries.
What is the self inductance of a coil if its inductive reactance is 12.56 Ohm at a frequency of 200 Hz?
Ans. 0.01 H.
What is the resistance of the inductive coil?
An inductive coil has resistance of 100Ω. When an ac signal of frequency 1000 Hz is fed to the coil, the applied voltage leads the current by 45∘.
How do you calculate frequency and resistance?
Calculate resistance from the new value of impedance, 144 ohms. Because the load is nonreactive, resistance R in ohms = X = 144 ohms at the higher frequency. Calculate the new value of power in watts at the higher frequency by solving I = V/X, = 240 volts/144 ohms = 1.667 amps.
What is the self inductance of a coil if its inductive?
Differences Between Mutual Inductance and Self Inductance
| Self-inductance | Mutual Inductance |
|---|---|
| Changing current in a coil induces an emf in itself and opposes the change in current. | Changing current in one coil induces emf in another coil, and opposes the change in current. |
| L = μr μ0 n2 A l | M = μr μ0 n1n2π r21 l |
What is the inductive reactance of a coil of inductance 10mh at a frequency 50hz?
The reactance of the coil at 50 Hz is 3.14 Ω.
How do you find the inductance of a coil?
The formula is: The micro henrys of inductance in a coil = (N^2)(D^2)/(18D + 40L) where “N” equals the number of rings in the coil, “D” equals the diameter of the coil and “L” equals the length of the coil.
How do you convert Hz to ohms?
You cannot. Hertz is the number of occurrences of a repeating event per unit of time. You can convert Hertz into ‘wavelength in cm’ with 1 Hz equal to 299792458 wavelength in cm. Ohms is a measurement of resistivity and is measured in Ohms-meter (Ω·m).
How do you find the frequency in hertz?
This frequency definition leads us to the simplest frequency formula: f = 1 / T . f denotes frequency and T stands for the time it takes to complete one wave cycle measured in seconds. The SI frequency unit is Hertz (Hz), which equals 1/s (one cycle per second).
