Enlist two properties of a polarized nerve fibre.

Explanation

### Step-by-Step Solution:

1. **Understanding Polarized Nerve Fibers**:
- Polarized nerve fibers are nerve cells that have a difference in electrical charge across their membrane when they are not actively transmitting signals. This state is known as resting potential.

2. **First Property - Resting Potential**:
- One key property of a polarized nerve fiber is that it has a resting potential of approximately -70 mV. This means that the inside of the nerve cell is more negatively charged compared to the outside.
