Induced V, due to self inductance?

In summary, induced voltage due to self inductance is the voltage produced in a circuit due to changes in the current flowing through it, caused by the self-inductance of the circuit. It differs from induced voltage due to mutual inductance, which is caused by changes in current in a nearby circuit. The magnitude of induced voltage is affected by inductance, current change rate, and resistance, and it can be reduced by decreasing inductance, minimizing current change rate, and increasing resistance. Some real-life applications include transformers, motors, generators, inductive proximity sensors, and circuit design for voltage regulation.

In a DC circuit(Yes, keep going), when current starts to flow, and that current needs a bit of time to stabilize to its maximum value. Since there is change in current(increase) there is an increasing magnetic field, a changing flux... that will induce a -V to the circuit. Eventually when current stabilizes at t0, the induced V due to self inductance = 0 right?

But, how does current stabilize when there is that -V opposing it? Would the PS apply more voltage?

FAQ: Induced V, due to self inductance?

1. What is induced voltage due to self inductance?

Induced voltage due to self inductance is the voltage that is produced in a circuit when there is a change in the current flowing through it. It is caused by the self-inductance of the circuit, which is the ability of a circuit to oppose changes in the current flowing through it.

2. How is induced voltage due to self inductance different from induced voltage due to mutual inductance?

Induced voltage due to self inductance is caused by the change in current within a single circuit, while induced voltage due to mutual inductance is caused by the change in current in one circuit affecting the current in a nearby circuit. Self inductance is a property of an individual circuit, while mutual inductance is a property of two or more circuits interacting with each other.

3. What factors affect the magnitude of induced voltage due to self inductance?

The magnitude of induced voltage due to self inductance is affected by the inductance of the circuit, the rate of change of current, and the resistance of the circuit. A higher inductance, a faster rate of change of current, and a lower resistance will result in a larger induced voltage.

4. How can induced voltage due to self inductance be reduced?

Induced voltage due to self inductance can be reduced by decreasing the inductance of the circuit, minimizing the rate of change of current, and increasing the resistance of the circuit. Using components with lower inductance, such as resistors instead of inductors, can also help to reduce induced voltage.

5. What are some real-life applications of induced voltage due to self inductance?

Induced voltage due to self inductance is used in many electronic devices, such as transformers, motors, and generators. It is also a key principle in the functioning of inductive proximity sensors, which are commonly used in industrial and automotive applications. Additionally, self inductance is important in the design of circuits to prevent unwanted voltage spikes and to regulate current flow.
