In a single state transistor amplifier, when the signal changes by 0.02 V, the base current change by 10uA and collector current by ` 10 mu `A. If collector load `R_c = 2k Omega and R_L = 10k Omega `, Calculate :
Input impedance,

Explanation

To calculate the input impedance of a single state transistor amplifier, we can follow these steps:

### Step 1: Understand the relationship between voltage, current, and impedance
The input impedance (Z_in) can be calculated using Ohm's law, which states that:
\[ Z = \frac{V}{I} \]
Where:
- \( V \) is the change in voltage (input signal)
- \( I \) is the change in base current
