PART OF LARGE & VARIED COLLECTION OF OVER 7500 ELECTRICAL ITEMS ACQUIRED & DOCUMENTED BY ONTARIO HYDRO IN 1960S. COLLECTION WAS THOUGHT TO BE LARGEST & MOST COMPREHENSIVE IN CANADA & WAS DONATED TO NMST IN 1992.
Function
INSTRUMENT USED TO MEASURE QUANTITY OF ELECTRICAL CHARGE.
Technical
EXAMPLE OF BALLISTIC GALVANOMETER WHICH LIKE OTHER GALVANOMETER HAS COIL WHICH ROTATES BETWEEN MAGNETS BUT DIFFERS IN HAVING LARGE MOMENT OF INERTIA. THIS ENABLES IT TO BE USED TO MEASURE QUANTITY OF CHARGE RATHER THAN CURRENTS (REF. 2).
