# Why do inductors shift current by the same amount?

• iScience
In summary, inductors shift current in an electrical circuit by creating a magnetic field that interacts with the flow of current. They store energy in the form of potential energy and release it back into the circuit when the current changes. The amount of current shifted remains the same due to the principle of conservation of energy, but can be affected by the inductor's inductance, the rate of current change, and the resistance of the circuit. Inductors can shift current in both AC and DC circuits, with different mechanisms in each type of circuit.

phasor diagrams: what happens @ R=0?

when R=0 and there is only the inductive impedance, what's the angle?

## 1. Why do inductors shift current in an electrical circuit?

Inductors shift current in an electrical circuit due to their ability to store and release energy in the form of a magnetic field. When a current flows through an inductor, it creates a magnetic field around the inductor. This magnetic field then reacts with the flow of current, causing a shift in the current.

## 2. How does an inductor store energy?

An inductor stores energy by creating a magnetic field when a current flows through it. This magnetic field stores energy in the form of potential energy, which can be released back into the circuit when the current changes or stops flowing.

## 3. Why does the amount of current shifted by an inductor remain the same?

The amount of current shifted by an inductor remains the same due to the principle of conservation of energy. The energy stored in the inductor's magnetic field must be conserved, so when the current changes, the amount of energy released from the magnetic field will be the same as the amount stored, resulting in the same amount of current being shifted.

## 4. What factors affect the amount of current shifted by an inductor?

The amount of current shifted by an inductor is affected by the inductance of the inductor, the rate at which the current changes, and the resistance of the circuit. A higher inductance value, faster rate of current change, and lower resistance will result in a larger amount of current being shifted.

## 5. Can inductors shift current in both AC and DC circuits?

Yes, inductors can shift current in both AC and DC circuits. In AC circuits, the current is constantly changing, which causes the inductor to continuously release and store energy. In DC circuits, the current may not change, but the inductor can still store energy in its magnetic field, causing a shift in the current when the circuit is turned on or off.
