A two wire transmission line has a capacitance of `20 Pf//m` and a characteristic impedance of `50 Omega`
What is the inductance per metre of this cable ?

Explanation

To find the inductance per meter of a two-wire transmission line given its capacitance and characteristic impedance, we can follow these steps:

### Step 1: Identify the given values
- Capacitance (C) = 20 picofarads per meter (Pf/m)
- Characteristic impedance (Z) = 50 ohms (Ω)

### Step 2: Convert capacitance to farads
Since 1 picofarad (pF) = \(10^{-12}\) farads (F), we convert the capacitance:
