A moving-coil galvanometer designed for measuring charge by detecting a surge of current. It has a heavy coil with minimal damping. When a surge of current is passed through the coil, the initial maximum deflection (the ‘throw’) is proportional to the total charge that has passed.
A galvanometer that measures the quantity of electricity Q, flowing during the passage of a transient current I, where
The value of Q is deduced from the deflection, θ, of the moving part of the instrument. For a moving-coil instrument, Q ∝ θ.
