What is an inductive resistive circuit?
What is an inductive resistive circuit?
A LR Series Circuit consists basically of an inductor of inductance, L connected in series with a resistor of resistance, R. The resistance “R” is the DC resistive value of the wire turns or loops that goes into making up the inductors coil.
What is a series resistive circuit?
A series circuit is a circuit in which resistors are arranged in a chain, so the current has only one path to take. The current is the same through each resistor. The total resistance of the circuit is found by simply adding up the resistance values of the individual resistors: I = V / R = 10 / 20 = 0.5 A.
How do you know if a circuit is resistive inductive or capacitive?
If both inductors and capacitors are present then simply find the equivalent impedance of the load network. If the imaginary part of the equivalent impedance is positive then the load is inductive, if it is negative then it is capacitive, and if it is zero then it is resistive.
What is the power factor of DC circuit?
Power factor is defined as the cosine of angle between the voltage phasor and current phasor in an AC circuit. It is denoted as pf. For an AC circuit, 0≤pf≤1 whereas for DC circuit power factor is always 1.
Why are houses wired in parallel instead of in series?
Parallel circuits are used in homes because loads can be operated on their own. For example, if a series circuit was used, the lights would be dimmer with the addition of more lights. A parallel circuit avoids that issue.
What is inductive load example?
Reactive/Inductive Load – An inductive load converts current into a magnetic field. Inductive reactance resists the change to current, causing the circuit current to lag voltage. Examples of devices producing reactive/inductive loads include motors, transformers and chokes.
What is the power factor of series R-L circuit?
Therefore we can conclude that the power factor of the L-r circuit is in between one and zero. Hence the correct answer is option C. Note: Power factor is an important concept of an AC circuit which can also be shown in terms of impedance of circuit and the power of circuit.
What is the power factor of LCR circuit?
1
where ω=2πfand f= frequency of AC source and C and L are the capacitance and the inductance in the circuit respectively. Therefore, the power factor of an LCR circuit at resonance is 1.
How does a series resistor and inductor circuit work?
Series resistor inductor circuit: Current lags applied voltage by 0o to 90o. The resistor will offer 5 Ω of resistance to AC current regardless of frequency, while the inductor will offer 3.7699 Ω of reactance to AC current at 60 Hz.
How is resistance connected to an inductive circuit?
In such circuit, resistance is considered as series element to the inductor. Consider the below figure in which a pure resistance is connected in series with pure inductance. This series combination is connected across an AC supply of voltage v = V m sin ωt.
How are inductive circuits used in an AC circuit?
AC Inductive Circuits. 1 AC Applied Across a Pure Inductor. A pure inductor has no resistance in the coil winding but has only inductance. This property of inductance is 2 Inductive Reactance. 3 Power and Power Factor in Inductive AC Circuit. 4 Series RL Circuit.
Are there inductive effects in a series RL circuit?
This guide covers Series RL Circuit Analysis, its Phasor Diagram, Power & Impedance Triangle, and several solved examples. In a purely resistive AC circuit, any inductive effects are considered negligible.
