Reactive current through inductive load produces -- Magnetic field
The voltage across a resistance is in phase with the current through the resistance because the resitance in non-reactive, i.e. non-inductive and non-capacitative. In the inductive case, the load resists a change in current. In the capacitative case, the load resists a change in voltage. In the resistive case, the load current follows the voltage with no delay, hence there is no phase differential.
A magnetic field is generated whenever a current is passing through a wire.
One ohm.
Real power is power that is used to do work. This is the power a light bulb uses to glow. Reactive power is power that is stored in one part of the AC voltage wave, and released in another. This causes the power to appear as a phase shift, and is generally caused by inductive or capactive loads. With regard to the power system, you can also get reactive power flowing due to unequal source voltages. Under these conditions, the apparent impedance of one source to the other will appear reactive/inductive, resulting in reactive power flow.
Because in an AC circuit, a capacitor opposes the change of voltage in at. At the peak of the voltage waveform, there is no change (it is nearly flat), so at this same point in time, the current waveform is at zero. Likewise, when the voltage waveform crosses zero, it is changing at its fastest rate, so the current is at its peak. If you draw these two waveforms next to one another, you will see the voltage has the appearance of being behind the current - hence the term 'lag'.
Its 'true power', expressed in watts, will be zero, while its 'reactive power', expressed in reactive volt amperes, will be the product of the voltage across the inductor and the current through it.
Resistance is a concept used for DC. the current through a resistance is in phase with the applied voltage Reactance is used for AC the current through a inductive reactance lags the applied voltage by 90 degrees. the current through capacitive reactance leads the applied voltage by 90 degrees. the net reactance is the difference between inductive and capacitive reactance
Electric field is produced
The voltage across a resistance is in phase with the current through the resistance because the resitance in non-reactive, i.e. non-inductive and non-capacitative. In the inductive case, the load resists a change in current. In the capacitative case, the load resists a change in voltage. In the resistive case, the load current follows the voltage with no delay, hence there is no phase differential.
This process is known as electrolysis.
The inductive effect is created through
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.
Did you know monkeys came from the moon
reactive metals can often be extracted by electrolysis where there ore is disolved into a solvent and an electric current is passed through.
it cannot be an element
Current flows through a wire and produces a magnetic field.
A:The inductor does not allow ac signal to pass through. It blocks ac and passes dc. If the switch is open, then the ac signal wont pass. If the switch is closed, then the ac signal will pass through the switch.AnswerIt is incorrect to say that an inductor 'does not allow' the passage of an alternating current. An a.c. current will pass through an inductor, although the inductor will limit the value of that current due to the inductor's inductive reactance. Inductive reactance, which is expressed in ohms, is directly-proportional to the inductance of the inductor and to the frequency of the supply. The value of the current is determined by dividing the supply voltage by the inductive reactance of the inductor.If the switch is connected in parallel with the inductor, then closing the switch will apply a direct short circuit across the inductor, and the resulting short-circuit current will cause the circuit's protective device (fuse or circuit breaker) to operate.
