Moving Coil (Potential Coil or Voltage Coil): This coil is wound with thin and light wire. The key reason for using thin wire is to maximize the number of turns within the available space More turns of wire result in a stronger magnetic field for a given amount of current passing through the coil. This coil is designed to be light because it needs to be sensitive to small changes in the magnetic field. When voltage is applied across this coil, it generates a magnetic field proportional to the voltage. Can you be precise why it is named as voltage coil how low resistance helps in measuring voltage across the loaf
