DESCRIPTION :
The almost universal use of Alternating Current (A.C.) in electric power transmission and consumption suggests that more time should be devoted to teaching the principles of A.C. in elementary physics. Student interest quickens when the practical advantage of A.C are shown. BESTO A.C. Acrylic meters for teaching and are especially suitable for use by students. These are economical, ruggedly constructed, have ample precision and are available in all commonly needed ranges. All our A.C. Rectangular panel meters are provided with stands.
