Hi,

The answer for your question is here;
The current lags the voltage by 90degree.
 

1. What is an inductor?

An inductor is an electrical component that stores energy in the form of a magnetic field. It is typically made of a coil of wire and is used in AC circuits to control the flow of current.

2. How does an inductor affect an AC circuit?

An inductor resists changes in current flow, so it can cause a phase shift in an AC circuit. This means that the voltage and current may not be in sync, and can result in a lag or lead in the circuit.

3. What happens to an inductor in an AC circuit?

In an AC circuit, the inductor experiences a constantly changing magnetic field due to the alternating current. This induces a voltage in the inductor, which can affect the overall circuit behavior.

4. Can an inductor be used to filter out specific frequencies in an AC circuit?

Yes, an inductor can be used in combination with other components, such as capacitors, to create a filter that blocks certain frequencies from passing through the circuit.

5. What are some common uses for an AC circuit with only an inductor?

An AC circuit with only an inductor can be used in power supplies, radio frequency circuits, and inductance-based sensors. It is also commonly used in electrical devices to smooth out current fluctuations and prevent damage to sensitive components.
