What circumstances is it possible for the rms current drawn from a certain source to have the same magnitude when an inductance is connected in series with a given impedance?
The same as what? when an inductor is connected in series with a resistor and a current passed through them, the voltages across the resistor and inductor are equal when the reactance is equal to the resistance: 2.pi.f.L = R
Why a inductor is used in series before diode instead of resistor?
An inductor will supply better current source.
What is the relationship between resistance and current in a resistive circuit?
:) It's connected together
The resistance that an inductor poses to the flow of ac?
An inductor has two properties. The first is resistance(measured in ohms), which is due to the length, cross-sectional area, and resistivity of the conductor from which it is wound. The second is inductance (measured in henrys), which is due to the length of the inductor, its cross-sectional area, the number of turns, and the permeability of its core.The inductor's resistance limits the value of current flowing through the inductor. The inductor's inductance opposes any change in current.
A red resistor draws more current than a blue resistor when they are connected to the same battery which resistor has the lower resistance?
The voltage of a battery goes as the current times the resistance (V=IR). Because the voltage is being held constant, the resistor that draws the most current will have the lower resistance.
What component limits current in a circuit?
A resistor or an inductor. The inductor limits transient current, not steady state current.

What is the relationship of current through the resistor and inductor in the LR parallel circuit?
When they are in parallel the same voltage appear across both. The resistor carries a current of V/R, the inductor carries a current of V/(jwL). So the current in the inductor is 90 degrees behind in its phase.
When an inductor and resistor are connected in parallel by how many degrees is the current flow through the resistor out of phase with the current flow through the inductor?
When a resistor and an inductor are both connected to an AC supply, the current in the resistor is in phase with the voltage, while the current in the inductor is a quarter-cycle (90 degrees) behind. Supposing they both draw 1 amp on a 12-volt AC supply. The resistor will dissipate 12 watts, while the inductor will dissipate no power. Any power that enters the inductor comes back to the generator in a later part of the cycle. But the current drawn from the supply is 1.414 amps, so this would be a load with a power factor of 0.707.
Why a inductor is used in series before diode instead of resistor?
An inductor will supply better current source.
How does ohm's law works in a resistor circuit?
Ohm's law states that voltage is resistance times current. In a resistor circuit, knowing two of voltage, current, or resistance, you can calculate the third.Actually, this applies to any circuit, be it resistor, capacitor, or inductor. Ohm's law still applies - it just gets more complex when the phase angle of current is not the same as the phase angle of voltage.
What is working principle of inductor?
A changing current through an inductor induces a voltage into the inductor, the direction of which always opposes the change in that current.So, in a d.c. circuit, an inductor will oppose (not prevent) any rise or fall in current, although the magnitude of that current will be determined by the resistance of that inductor, not by its inductance.In an a.c. circuit, because the current is continuously changing both in magnitude and in direction, it acts to continuously oppose the current due to its inductive reactance. Inductive reactance is proportional to the inductance of the inductor and the frequency of the supply. The vector sum of the inductive reactance of the inductor and the resistance of the inductor, is termed the impedance of the inductor. Inductive reactance, resistance, and impedance are each measured in ohms.
Why is there no flow of electric current between 2 objects of equal resistance?
I am not sure how the two objects of equal resistance are supposed to be connected. But for a current to flow, for example across a resistor, there must be a voltage difference between the terminals of this resistor.
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.
What is the difference between resistance and insulation?
Resistor is a current a insulator is a not conductive and conductors can conduct.

What is the difference between a resistor and an inductor?
Both a resistor and an inductor are electrical components designed to impede the unregulated flow of electricity. Where they differ is that inductors store energy in their induction coils which forms a magnetic field that focuses energy by the principle of inductance. As electricity passes into the inductor, current will slowly rise to a specified level. A resistor simply impedes the flow of electricity according to its property, but does not store energy. It also does not control the rate at which the current changes, it just changes the current allowed to pass through.
