What is the name of the meter that is used to measure current?
Electrical current is measured with an "ammeter". (The unit of current is "ampere". Measure it with an 'ampere-meter' ==> 'amp-meter' ==> 'ammeter'.)
The meter movement in an illumination meter measures?
current
How does work ohmmeter?
ANY METER needs some kind of current flow to operate. Internal in the meter there are batteries that provide current that when passed trough a resistor will develop voltage as a function of the current. the meter will read this current and display the resistor size to cause this current to flow.
Where does the current come from that moves the needle on an analog clamp on meter?
A: Directly from whatever you are measuring as a Small current to move the coil to indicate current flow. That current can be calibrated to read voltage or current on the meter itself
What effect if any does connecting an ammeter in series with a resistor in a circuit have on the current through the resistor?
The Amp meter was design to allow current flow through the meter to measure with a minimal alteration to the original circuit. That is the ideal world, in reality the meter has some resistance and will lower the current flow. The multiple current setting on most meter will reduce the effects caused by the meter but you must be careful not to damage the meter by reading to high for the setting.

Why should you put the meter on the negative side when measuring current?
A meter can be used both on the positive or negative side of a circuit when measuring current. The current going to a load should be equal to the current coming back from the load. When measuring DC current, make sure the meter should be more than adequete to be placed in series with the circuit. Otherwise, use a clamp-on meter.
What is the maximum current capacity measured by a 100 amp meter?
A 100 amp meter can measure a maximum current capacity of 100 amps.
What Do Amps Measure?
You can measure the electrical current with an amp meter. Amperage measures the current flow.
What is the meaning of the math word meter?
A metre is the basic SI unit of length, but is often misspelt as 'meter'. A meter might refer to either a measuring device, e.g. a Volt meter measures the energy possesed by the current in a current in a circuit.
When you say your increasing the range of an ammeter what exactly are you doing?
You're connecting a resistance in parallel with the ammeter, so that when the meter and the additional resistor are inserted into a current-carrying circuit, a part of the current goes through the meter, and the rest of the current bypasses the meter and goes through the resistor instead. If you know exactly how much the split is, then you can calculate the larger total current from the smaller number that you read on the meter, so the meter is now able to measure and display more current than it could before ... the range of its measurement ability has been extended. Example: -- You know the resistance of the meter. -- You connect a resistor with exactly that same resistance in parallel with the meter. -- Now 1/2 of the current goes through the meter and 1/2 goes through the resistor. -- The total current is exactly double what you read on the meter.
