The dynamic plate resistance of a triode valve is `10 kOmega`. Find the change in the plate current if the plate voltage is changed from `200 V` to `220 V`.

Explanation

To solve the problem, we need to find the change in the plate current (ΔIp) when the plate voltage (Vp) changes from 200 V to 220 V, given that the dynamic plate resistance (Rp) is 10 kΩ.

### Step-by-Step Solution:

1. **Identify the given values:**
- Dynamic plate resistance, \( R_p = 10 \, k\Omega = 10 \times 10^3 \, \Omega = 10^4 \, \Omega \)
- Initial plate voltage, \( V_{p1} = 200 \, V \)
- Final plate voltage, \( V_{p2} = 220 \, V \)
