If `theta = 270` degree, then the value of `epsi` is ?

Options

A. Infinite
B. `-epsi _(0)`
C. Between Zero and 1
D. One

Explanation

To solve the problem, we need to find the value of the induced electromotive force (emf), denoted as `e`, when the angle `theta` is given as 270 degrees.

### Step-by-Step Solution:

1. **Identify the formula for induced emf**:
The induced emf (e) is given by the formula:
\[ e = e_0 \sin(\theta) \]
where \( e_0 \) is the maximum induced emf and \( \theta \) is the angle.

2. **Substitute the given value of theta**:
We are given that \( \theta = 270^\circ \). We can substitute this value into the formula:
\[ e = e_0 \sin(270^\circ) \]

3. **Calculate sin(270 degrees)**:
The sine of 270 degrees is a known value:
\[ \sin(270^\circ) = -1 \]

4. **Substitute the value of sin(270 degrees)**:
Now we can substitute this value back into the equation for e:
\[ e = e_0 \cdot (-1) \]
This simplifies to:
\[ e = -e_0 \]

5. **Conclusion**:
Therefore, the value of \( e \) when \( \theta = 270^\circ \) is:
\[ e = -e_0 \]

### Final Answer:
The value of `e` is \(-e_0\).
