| HOT WIRE METER
(0458) |
| A simple demonstration meter model that indicates the current flowing across its terminals on the basis of heating effects of current, i.e., demonstrates the heating effects of current. A resistance wire is fixed across two 4mm socket terminals mounted on insulated plastic base. Flow of current through the wire heats it that results in its elongation. This elongation is calibrated using a simple mechanism to move the pointer indicating the current flowing through resistance wire. Transparent acrylic window mounted on top provides clear view to its working. Clamping arrangement provided at the rear makes it easily mountable on a suitable retort stand for demonstration to a group of students. |
