DC current has no effect on the inductor(can be considered as a short circuit) as the current does not change in a DC supply voltage this one just produces a magnetic field which remains constant , as the magnetic field is not varying no emf is induced in the circuit , so literally it has no effect on the circuit when the supply is of DC voltage.
when an alternating current is set up in a circuit , the Alternating current brings a magnetic field in the inductor which is variable (since the current is varying...) this variable magnetic field induces an emf in the circuit (back emf) which opposes the cause that is producing the change (lenz's law)
explanation consider a circuit with an inductor connected to an AC voltage
during the positive half cycle when the voltage increases the current also increases in the circuit [take the current direction as clockwise] this causes a variable increasing magnetic field in the inductor , this magnetic field in turn induces current in the circuit which is opposing the increase in the current flow from the original source, the inverse happen during the decreasing half of the half of the positive cycle , here the induced current adds up with the decreasing current opposing the cause that produced this back current (cause :- decrease in current changes the magnetic field so the induced current is produced ..... it is opposing the change because :- the induced current either decreases the increasing current or increases the decreasing current )

Are capacitors and inductors active elements?
Capacitors and inductors are considered passive elements, not active elements, because capacitors and inductors do not supply or amplify energy. An example of an active element is a battery, which supplies energy to a circuit.
What do you need to build a circuit?

How does energy flow s through a electromagnetic circuit?
In an electromagnetic circuit, energy flows from a power source through the circuit components such as resistors, capacitors, and inductors. The energy is transferred through the circuit as electrical currents and magnetic fields, with some energy converted into other forms such as heat in resistors or stored in capacitors and inductors. Ultimately, the energy is dissipated or utilized to perform work within the circuit.
How do you make a simple circuit?
Before constructing a simple circuit we must first have in mind which type of source is to be supplied to the circuit . A simple circuit may consist of the following components such as capacitors, resistors , inductors etc
How we choose capacitor and inductor for any circuit that we are going to work on it?
Most circuit designers usually choose capacitors over inductors to perform similar tasks
What does the M mean on a electrical circuit?
It most likely stands for the Mutual Inductance seen between two inductors.
Different types of inductors?
There are a variety of types of inductors. These include coupled inductors, multi-layer inductors, ceramic core inductors, as well as molded inductors.
What is meant by tank circuit in hartley oscillator?
it is the circuit that is responsible for producing oscillation.In hartley it is two inductors connected in series and a capacitor parallel to this series connection.Without tank oscillator tends to act as as an amplifier.
