Ampère balance

Definition

Electronics

  • An ammeter which operates by having a current pass through two nearby coils connected in series. One of the coils is fixed, while the other is attached to the arm of a balance. The attractive force between the coils is counterweighed by the force of gravity acting on a known weight on the arm of the balance, which in turn indicates the current strength on its scale. Also called Kelvin balance, or current balance.
