Assertion: The bending of an insulated wire increase the resistance of wire
Reason : The drift velocity of electron in this wire decreases

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step 1: Understand the Assertion
The assertion states: "The bending of an insulated wire increases the resistance of the wire."

- Resistance (R) of a wire is given by the formula:
\[ R = \rho \frac{L}{A} \]
where \( \rho \) is the resistivity of the material, \( L \) is the length of the wire, and \( A \) is the cross-sectional area.

- When a wire is bent, the effective length of the wire may change depending on how it is bent, but typically, bending does not increase the resistance. In fact, if the wire is bent in a way that increases its cross-sectional area or reduces its effective length, the resistance can decrease.

### Step 2: Analyze the Reason
The reason states: "The drift velocity of electrons in this wire decreases."

- Drift velocity (\( v_d \)) is given by the equation:
\[ v_d = \frac{I}{nAq} \]
where \( I \) is the current, \( n \) is the number density of charge carriers, \( A \) is the cross-sectional area, and \( q \) is the charge of an electron.

- The drift velocity is influenced by the current and the cross-sectional area of the wire. When the wire is bent, the drift velocity does not necessarily decrease just because the wire is bent. The relationship between bending and drift velocity is not direct, and bending alone does not imply a decrease in drift velocity.

### Conclusion
- The assertion is **incorrect** because bending does not necessarily increase resistance.
- The reason is also **incorrect** because bending the wire does not directly decrease the drift velocity of electrons.

### Final Answer
Both the assertion and the reason are incorrect.
