When the voltage between emitter and the base `V_(EB)` of a transistor is chaged by 5 mV while keeping the collector voltage `V_(CE)` fixed when then its emitter current changes by 0.15 mA. Calculate the input resistance of the transistor.

Explanation

To calculate the input resistance of the transistor, we will follow these steps:

### Step 1: Understand the relationship between voltage, current, and resistance
The input resistance \( R_{in} \) of a transistor can be defined using Ohm's Law, which states that resistance is the ratio of voltage to current. In this case, we can express the input resistance as:
\[ R_{in} = \frac{V_{EB}}{I_E} \]
where \( V_{EB} \) is the change in emitter-base voltage and \( I_E \) is the change in emitter current.
