The significance of self inductance L is the same as of that of ……in the linear motion __

Options

A. mass
B. velocity
C. acceleration
D. displacement

Answer

To solve the question regarding the significance of self-inductance \( L \) in relation to linear motion, we can follow these steps:

### Step 1: Understand Self-Inductance
Self-inductance \( L \) is a property of an inductor that quantifies its ability to oppose changes in the current flowing through it. When the current changes, the inductor generates an electromotive force (emf) that opposes this change, according to Lenz's Law.

### Step 2: Identify the Concept of Inertia in Linear Motion
In linear motion, inertia is the property of an object to resist changes in its state of motion. This means that an object at rest will stay at rest, and an object in motion will continue to move at a constant velocity unless acted upon by an external force.

### Step 3: Compare Self-Inductance and Inertia
Both self-inductance and inertia share a common characteristic: they resist changes. Self-inductance resists changes in current, while inertia resists changes in velocity. Therefore, the significance of self-inductance \( L \) is analogous to the significance of mass in linear motion.

### Step 4: Conclusion
Based on the comparison, we conclude that the significance of self-inductance \( L \) is the same as that of **mass** in linear motion.

### Final Answer
The significance of self-inductance \( L \) is the same as that of **mass** in linear motion.
