Hint: To answer this question, we first need to understand what is current. A stream of charged particles, such as electrons or ions, travelling through an electrical conductor or space is known as an electric current. It's the net rate of electric charge flow through a surface or into a control container that's monitored. Charge carriers are the moving particles, and depending on the conductor, they might be one of numerous sorts of particles.
Complete answer:
Galvanometer: A galvanometer is a device that detects and measures tiny currents. It's typically found in potentiometers and bridges, where it's utilized to show minor deflections. It's an electromagnetic device with a high sensitivity. It can detect very small currents, down to a few microamperes.
Current sensitivity: The deflection induced in the coil of a galvanometer per unit passage of electric current through it is known as current sensitivity.
sensitivity at the moment =
denotes the magnetic field intensity in which the coil is hanging.The coil's area is denoted by the letter . The restoring torque per unit twist of the suspension string is and is the number of twists in the coil.
So, we conclude that the deflection produced in a moving coil galvanometer when unit current flows through it is defined as its current sensitivity.
Note: Voltage sensitivity is a measurement of an appliance's responsiveness to a voltage transform applied across it. An ammeter with a galvanometer is a type of ammeter.It's a device that detects and measures electric current. As a result, a galvanometer's voltage sensitivity is defined as the deflection per unit voltage across the galvanometer.
