What is the phase angle of an ohm inductor in series with an ohm resistor connected to a 5 KHz source?

You need to provide values of resistor and inductor etc to find the phase angle.


What is the resistance of an inductor called?

The resistance of an inductor is generally referred to as the series resistance, sometimes noted as RL. Note that resistance is a DC measurement and that an "ideal" textbook inductor has an RL of 0. The reactance of an inductor is an AC measurement which measures the reaction of a component's current flow to an alternating voltage and is frequency dependent and directly proportional to the inductor's inductance, measured in Henrie's. The impedance is most commonly used when talking about inductors or capacitors and is a combination of resistance and reactance.


What is the inductive reactance of a 0.5 H inductor connected with a 1000 ohm resistor in an AC Circuit supplied with 48 VAC at 100 Hz?

The reactance of an inductor depends only on its inductance and the frequency.The voltage and any series components are irrelevant.Z = j 2 pi f L = j 2 pi (100) (0.5) = 314.16 ohmsreactive


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.

What is the time constant of a 50mH inductor in series with a 200 ohm resistor?

The time constant (τ) of a circuit consisting of an inductor (L) and a resistor (R) in series is given by the formula τ = L/R. In this case, with L = 50mH and R = 200 ohms, the time constant would be τ = (50mH) / (200 ohms) = 0.25 milliseconds.

An inductor will supply better current source.


How does current flows when inductor n capacitor r in series?

The stronger the magnetic field on your inductor the greater amount of current you will have flowing through your series circuit.


What are the difference between rl and RC circuit?

RL circuit consists of a resistor and an inductor connected in series, while an RC circuit consists of a resistor and a capacitor connected in series. In an RL circuit, the time constant is determined by the resistance and inductance, while in an RC circuit, the time constant is determined by the resistance and capacitance. RL circuits respond to changes in current, while RC circuits respond to changes in voltage.


What happens to a light bulb when put in series with a inductor?

When you put a light bulb in series with a inductor, the inductive reactance of the inductor reduces the current available to the light bulb, making it less bright. For this effect to be noticed, however, you need a very large inductor. To cut the current in a 60W bulb at 120VAC/60Hz by one half, for instance, you need an inductor around 0.6 henrys.


Why inductor use in series capacitor in parallel?

That depends on the type of circuit you are talking about. Sometimes both an inductor and capacitor are both in parallel with each other. This is called a tank circuit. Sometimes they are both used in series. These are both examples of resonant circuits. Sometimes the inductor can be in parallel with an applied voltage and the capacitor in series. This is a form of high pass filter. On the other hand, the inductor can be in series and the capacitor in parallel to for a low pass filter.


How much is zt for a 100 ohms resister in series with 100 ohms inductor?

The total impedance ( Z_t ) of a circuit with a resistor (R) and inductor (L) in series can be calculated using the formula ( Z_t = R + jX_L ), where ( X_L = \omega L ) is the inductive reactance. For a 100-ohm resistor and a 100-ohm inductor, the impedance will depend on the frequency ( f ) of the AC current. If the inductance and frequency are such that ( X_L = 100 ) ohms (e.g., at a specific frequency), then ( Z_t = 100 + j100 ) ohms, resulting in a magnitude of ( Z_t = \sqrt{100^2 + 100^2} = 100\sqrt{2} ) ohms.

Inductor works in direct current?

Yes, an inductor works with direct current. It is called an electromagnet. Of course, a practical electromagnet has series resistance, otherwise the current in the inductor would increase to the limit of the current/voltage source.
