Power dissipated in pure inductance will be-

Options

A. `(1)/(2Li^(2))`
B. `2Li^(2)`
C. `(Li^(2))/(4)`
D. zero

Answer

To solve the question regarding the power dissipated in pure inductance, we can follow these steps:

### Step 1: Understand the Components
In an AC circuit, we have three main components: resistors, capacitors, and inductors. Each of these components behaves differently when an alternating current (AC) flows through them.

**Hint:** Remember the roles of resistors, capacitors, and inductors in an AC circuit.

### Step 2: Power Dissipation in Components
Power dissipation occurs primarily in resistors. Resistors convert electrical energy into heat, which is where power is dissipated. Capacitors and inductors, on the other hand, do not dissipate power in the same way.

**Hint:** Focus on how each component interacts with AC current and how they handle energy.

### Step 3: Behavior of Inductors
Inductors store energy in the form of a magnetic field when current flows through them. They do not convert electrical energy into heat, which means they do not dissipate power.

**Hint:** Recall the concept of energy storage in inductors versus energy dissipation.

### Step 4: Conclusion
Since inductors do not dissipate power, the power dissipated in a pure inductance is zero.

**Final Answer:** The power dissipated in pure inductance is **0 watts**.

### Summary of Steps:
1. Identify the components in an AC circuit.
2. Understand how power is dissipated in resistors.
3. Recognize that inductors store energy rather than dissipate it.
4. Conclude that the power dissipated in pure inductance is zero.
