The readings on an ammeter indicate the current being drawn by a load in a circuit.
This load is basically a resistance to current flow. The higher the resistance, the lower the current.
The supply voltage has a direct effect on current flow. The higher the voltage applied, the higher the current will be.
So the readings will vary on the ammeter according to fluctuations in load and or resistance of the circuit and the applied voltage.
an ideal ammeter will have zero resistance
It is called a Tell Tale because it tells you the current of the circuit.
The scale of each meter manufacturer will be different. You'll need to refer to the owners manual to determine the proper setting. Remember that an ammeter is used INLINE with the electrical device to determine current draw. Do NOT put the test leads of an ammeter across the two leads of the service voltage.
The number of Neutrons in an isotope will always be different.
No, your live (brown) cable takes the load and pulls the amps from the supply, not the neutral. Your ammeter should be clipped on the live to get a correct reading.
A galvanometer is a type of ammeter an instrument for detecting and measuring electric current. A galvanometer can be converted into ammeter by connecting resistance in parallel with it.
-- In a series circuit, no matter where you install the ammeter, it will always read the same current. -- In a parallel circuit, the ammeter may read a different current when it's moved to a different parallel branch.
An ammeter is always connected in series in the circuit.
Series.
First readings always come fro the Lectionary.
HOW TO CONNECT AN AMMETER Always connect an ammeter in SERIES in a circuit. Always ensure that the ammeter has a higher reading range than the expected current load, including start-up spikes. An ammeter expected to read a steady current of 13A should have a max range of 20A.
An ammeter is always connected in series and a vlotmeter in parallel
the power needs to go "through" the ammeter for it to accurately measure the amount of amps being used. unlike a volt gauge that just measures what the system has for voltage. volts and amps are totally different.
Different intensities.
The Voltmeter is used to measure the electrical potential difference between two points... so it's no use to connect it in Series , because the electrical potential difference between two points at the same line is zero ==> the readings will always be zero. The Ammeter is used to measure the electric current in a circuit... so it's no use to connect it in Parallel , because you want to know the current flowing in this wire. note the internal Resistance of the Ammeter is very little and very high for the Voltmeter --> so they will not affect the circuit.
Direction only. If you reverse the connections to your voltmeter or ammeter you get the same size readings but the directions are indicated to be the opposite way around, by reversal of sign.
No, an ammeter should never be placed in parallel with a component - it should always be placed in series, so that the current through the component is measured.If you place an ammeter in parallel with a component, you create a short circuit around the component. Depending on the rest of the circuit, you could damage the circuit, damage the ammeter, create a fire, etc. You certainly will affect the current through the component, and that is not what you want to accomplish.
