D and e are the line wires and the circuit is completed through the ammeter to show whether we are generating electricity.
Each circuit is provided with a separate rheostat and ammeter.
The ammeter indicated only half as much as before, that is .008 ampere.
ammeter should show three to five amperes charge with lamps burning.
He invented an ammeter, voltmeter, &c., in conjunction with Professor Perry.
A relay snapped, and instantly the ammeter jumped to read 4500 amperes.
But his chuckle was not so rotund, and he was very attentive to the ammeter.
In fact, a voltmeter is an ammeter which has had its shunt removed or disconnected.
Connect an ammeter in the plate- or B-circuit, of the tube so as to measure the plate-circuit current.
This current may be controlled by a suitable resistance and measured by an ammeter.
An instrument that measures the strength of an electric current, indicating it in amperes. Ammeters typically include a galvanometer; digital ammeters typically include A/D converters as well. Compare ohmmeter, voltmeter.
