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.

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.
What component limits current in a circuit?
A resistor or an inductor. The inductor limits transient current, not steady state current.
Can a transistor can act like resistor capacitor inductor?
A transistor acts like a resistor when Gate is connected to Source.
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.
What is the difference between resistance and insulation?
Resistor is a current a insulator is a not conductive and conductors can conduct.
What are the difference between rl and RC circuit?
RL circuits involve a resistor and inductor in series. RC circuits involve a resistor and capacitor in series. You can see where the acronyms come from.
Difference between variable resistor and rheostat?
The difference between a variable resistor and a rheostat is the same as the difference between six and half a dozen.
What is the difference between coil inductor solenoid?
Physicall no difference.But inductor uses ac and solinoid uses dc.
Why a inductor is used in series before diode instead of resistor?
An inductor will supply better current source.
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.
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?

A resistor or an inductor. The inductor limits transient current, not steady state current.
What are components in smart chip?
capacitor,transistor,resistor,inductor
What happens when a inductor reaches a steady state?
An inductor looks like a piece of wire to DC. It will thus look like a resistor, and inductor properties do not apply.
What the difference between Transistor and resistor?
The difference between a Transistor and a Resistor is that a transistor is designed to amplify the electrical current, whereas a Resistor is designed to reduce the electrical current.
Why current and voltages are in phase in resistor?
1) in inductor there is generation of magnetic field due to flow of current . so there is phase difference in voltage and current . 2)in capacitor there is storage of charges. there is phase diff. 3)But in case of resistor there is no such things are happend . it is only a power dissipating element.therefor there is no phase difference between current and voltage.
Can a transistor can act like resistor capacitor inductor?
A transistor acts like a resistor when Gate is connected to Source.
