What are the Advantages and disadvantages of current meter?
disadvantage of current meter
How does the technique for measuring current with DMM differ from measuring voltage?
current is measured with the meter in series and voltage is measured with the meter in parallel of the load
What is a current measured in?
Ammeters (amps) An Ammeter is a meter for measuring electrical current, the unit of which is the Ampere (amp)
What does a inductive ammeter do?
It measures current by creating a coil around the current carrying wire. Current flowing in the wire induces a current in the amp-meter proportional to the current flowing in the wire.
Why would never measure resistance in a circuit carrying a current?
If the circuit is carrying current then that means that the load (resistance) is in the circuit. if an ohm meter is connected in the live circuit then there would be some voltage drop at the ohm meter but as the meter has very less resistance, this would damage the instrument.

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
Advantage and disadvantage of orifice meter?

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.

current is measured with the meter in series and voltage is measured with the meter in parallel of the load
What Do Amps Measure?
You can measure the electrical current with an amp meter. Amperage measures the current flow.
Why high-voltage current measurement using a common meter is not recommended?
A common meter cannot withstand high voltage current if it is not rated to do so it will be damaged due to excessive current
