Question

Answer

Just like inertia tends to maintain its original state of motion or rest.inductance do the same it wants to maintain it state. inertia resists any relative motion.inductance also do the same.so L is equivalent to inertia.

Answer

The inductance has a similar 'resistance'effect to that of the mass:If you apply voltage it tries to resist it, while if you stop the applied voltage,it tends to 'resist'this stop via the back emf....mass has inertia.

Answer

Inductance is a fundamental property of electrical circuits that describes the ability of a circuit element to resist changes in current. It is measured in units called henries (H) and is denoted by the symbol L. Inductance is a crucial factor in the behavior of electrical circuits and plays a significant role in various applications.

Inductance and Inertia:

Inductance can be understood by drawing an analogy to the concept of inertia in mechanics. Inertia is the property of an object that resists changes in its velocity. Similarly, inductance is the property of an electrical circuit that resists changes in current. This analogy helps in understanding the role of inductance.

1. Resisting Changes in Current:

Inductance resists changes in current by storing energy in a magnetic field. When the current flowing through an inductor changes, the magnetic field associated with the inductor also changes. The energy stored in the magnetic field opposes the change in current, acting as a 'reservoir' of energy. This is similar to how inertia opposes changes in velocity.

2. Delaying Current Changes:

Inductors introduce a delay in the response of current in a circuit. When a voltage is applied across an inductor, it takes some time for the current to reach its final value. This delay is due to the energy required to establish and change the magnetic field. Just like inertia causes a delay in the acceleration of an object, inductance causes a delay in the change of current.

3. Storing and Releasing Energy:

Inductors store energy in their magnetic fields, which can be released back into the circuit when the current changes. This property is utilized in various applications, such as inductive energy storage in power supplies or flyback transformers. In this sense, inductance can be seen as equivalent to the energy stored in the magnetic field.

Conclusion:

Inductance plays a role similar to inertia in mechanics, resisting changes in current and causing delays in the response of electrical circuits. It stores energy in its magnetic field and releases it when the current changes. Understanding the concept of inductance and its relationship to inertia helps in grasping its significance in electrical circuits. Thus, the correct answer is option 'C' - inductance is equivalent to inertia.
