Define ammeter

Electric currents are measured in amperes (A), hence the name. Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as milliammeters or microammeters. Ammeter definition , an instrument for measuring current in amperes. Define ammeter : an instrument for measuring electric current especially in amperes.


A device called an ammeter is used to measure current.

Ammeter : Ammeter ,, instrument for measuring either direct or alternating electric current, in amperes.

AMMETER meaning - AMMETER definition - AMMETER explanation.

Ammeter means Ampere-meter which measures ampere value. English dictionary definition of ammeter. An instrument for measuring electric currents in amperes. The meter uses for measuring the current is known as the ammeter. The current is the flow of electrons whose unit is ampere.


Hence the instrument which measures the flows of current in ampere is known as ampere meter or ammeter. The ammeter is in series with the lamp. Why do we hook those up in parallel?


Voltage, remember, is defined to be the difference between electric potential at two points in . The fifth class comprises the electromagnetic or electro-dynamic instruments, which are virtually very sensitive . Find out information about ammeter. Looking for online definition of ammeter in the Medical Dictionary ? Meaning of ammeter medical term. Multimeter definition , a device consisting of one or more meters, as an ammeter and voltmeter, used to measure two or more electrical quantities in an electric circuit, as voltage, resistance, and current. However, unlike the ideal voltmeter, the ideal ammeter has zero internal resistance, so as to drop as little voltage as possible as electrons flow through it.


Note that this ideal resistance value is exactly opposite as that of . In this case the shunt, a manganin resistor of accurately known resistance, is placed in parallel with the moving coil galvanometer , thus all of the current to be measured will flow through it.
