What is the SI unit of Self Inductance ?

Options

A. Henry
B. T
C. `TmA^(-2)`
D. `TmA`

Explanation

To determine the SI unit of self-inductance, we can follow these steps:

### Step 1: Understanding Self-Inductance
Self-inductance is a property of a coil (or inductor) that quantifies how much electromotive force (EMF) is induced in the coil due to a change in current flowing through it.

### Step 2: Identifying the SI Unit
The SI unit of self-inductance is defined as the henry (symbol: H).

### Step 3: Definition of One Henry
One henry is defined as the amount of self-inductance in a coil when a current of one ampere flowing through it produces a flux linkage of one weber-turn.

### Step 4: Analyzing the Options
Given the options:
1. Henry
2. Tesla
3. Tesla meter
4. Ampere squared per watt
5. Tesla meter ampere

From the definition, we can see that the correct answer is "Henry".

### Conclusion
Thus, the SI unit of self-inductance is **Henry**.
