ammeter's Usage Examples:

- For switchboard use i n Ammeter Kelvin ' electric supply stations where space is valuable, James White instruments of the type called edgewise ammeters Ltd.

Hot-wire ammeters are, however, liable to a shift of zero, and means are always provided by some adjusting screw for slightly altering the sag of the wire and so adjusting the index needle to the zero of the scale.

In its simplest form an electromagnetic ammeter consists of a circular coil of wire in which is pivoted eccentrically an index needle carrying at its lower end a small mass of iron.

Hence we may classify ammeters into (1) Thermal; (2) Electromagnetic, and (3) Electrodynamic instruments.

Another form of hot-wire ammeter is a modification of the electric thermometer originally invented by Sir W.

The potential difference of the ends of the low resistance is at the same time measured on the potentiometer, and the quotient of this potential difference by the known value of the low resistance gives the true value of the current passing through the ammeter.

The calibration of ammeters is best conducted by means of a series of standard low resistances and of a potentio meter.

The ammeter to be calibrated is placed in series with a suitable low resistance which may be �i ohm, �oi ohm, �ooi ohm or more as the case may be.

Such an instrument is called a shunted movable coil ammeter, and is represented by a type of instrument shown in fig.

From this it follows that hot-wire ammeters are generally not capable of giving visible indications below a certain minimum current for each instrument.

Until they received them they were using huge old wooden voltmeters and ammeters from the 1950s.

A steady continuous current is then passed through the ammeter and low resistance, placed in series with one another and adjusted so as to give any required scale reading on the ammeter.
