Because inductance is only related to alternating current. Direct current doesn't induce eletrical current on a secondary coil placed on a primary coil, because there is no frequency generated by direct current, and all you get is a single electrical current flowing through the wire without interfering with a coil placed near to the primary coil. What makes all the difference is the cycles per second that only alternating current can generate.

Why you use capacitors in power supply?
You use a capacitor to store electrostatic energy. You use an inductor to store electromagnetic energy. You use a resistor to dissipate electrical energy.
Where should ac or DC supply be used?
The type of power supply being used (AC or DC) should match the power requirements of the device it will be supplying power to.
What happens if a 200 mA power supply is used on a circuit needing 2 amp?
If a 200 mA power supply is used on a circuit needing 2 amp it would overload the power supply. Two amps equates to 2000 milliamps. Trying to pull 2000 milliamps from a device that is only capable of supplying 200 milliamps is not advisable. The excessive current draw would most likely burn the wires open and render the power supply useless.
What is the purpose of a inductor?
The purpose of an inductor is to store and release energy in the circuit usually in order to induce a phase shift in the voltage or current passing through it. Inductor stores energy in the magnetic field.
What does an electrical choke do?
A choke is an inductor. The impedance of an inductor is dependent on the frequency of the current flowing through it. The greater the frequency, the higher the impedance. Therefore an inductor when used as a choke blocks the flow of high frequency current (by presenting a high impedance), while allowing low frequency or direct current to flow through it. Its function is to block ("choke") high frequencies while passing low frequencies.
Why a inductor is used in series before diode instead of resistor?
An inductor will supply better current source.
Why inductor is used in electrical circuit?
To improve the power factor
Why is an inductor used for?
what is an inductor used for
What is the function of an inductors which is installed at output of 1.5V power supply?
An inductor resists a change in current, so it can be installed in a power supply lead to reduce the effects of changing input voltage, such as what happens in a rectifier when the diode starts conducting again. Often, inductors and capacitors are used together to build a filter.
Why there are only RC filters and not RLC filters used with IC.why inductor is not used?
The inductor is a component which produces inductance. This inductance which opposes any change of current through it, so if any changes occurred in an IC the output will be changed. so inductor is not used.
Why electrical appliances use inductors?
An inductor is commonly used for filtering current in electronic items. They are used to block AC current when DC is allowed through. They are also used to separate signals of different frequencies.
Why inductor are used in CKT?
inductor is used in ckt because it will work as controling current device
What happens if you put a inductor instead of the capacitor at the capacitor start motor?
An inductor can be used, in principle, but it has to be the right inductance, it will waste more power than a capacitor, and the motor would rotate the opposite way.
May I know the properties of an inductor?
Some of them are: 1. Inductor temporarily stores energy in form of magnetic field. It is given by E=½LI² here L is inductance & I is current. 2. Inductor causes current to lag voltage by 90°. 3. Inductor consumes reactive power. 4. Inductor oppose current change in circuit for AC only. Fo DC it act as simple wire. 5. Inductors are used for blocking the AC while passing the DC. They are known as chokes. 6. Inductors are used to create magnetic fields in electrical machines for the purpose of energy conversion.
Can any power supply be used on a Pentium 4 processor?
Yes, almost every PSU has enough power to supply a P4 CPU. It depends on the total load, not only on the CPU.
Is ATX power supply can be used in place of AT power supply?
No because they have different connectors.
Why you use capacitors in power supply?
You use a capacitor to store electrostatic energy. You use an inductor to store electromagnetic energy. You use a resistor to dissipate electrical energy.
