What is a dead beat galvanometer?

Explanation

### Step-by-Step Solution:

1. **Definition of a Deadbeat Galvanometer**:
A deadbeat galvanometer is an instrument used to measure electric current, which is designed to quickly dampen oscillations in its coil.

2. **Functionality**:
When current flows through the coil of the galvanometer, it experiences oscillations due to the torque produced by the magnetic field. This is a typical behavior of galvanometers.
