What is the instrument called that measures current?
The instrument used to measure electrical current is called an ammeter, which is actually a shortened form of 'amp meter'. The current is measured in amperes. In scientific labs, a much more sensitive instrument called a galvanometer is used to measure very small currents.
Why must you make current flow through the meter in order to measure it?
You don't. ...unless you want to directly measure the current in a circuit branch. That's the purpose of an ammeter. You can also use a volt meter if you know the resistance of a resistor in that branch to determine current (assuming DC circuit here) - current = voltage / resistance. This may be more useful for circuitry that is on a breadboard, since inserting an ammeter may not be practical.
What are some precautions do you take when using a milliammeter?
1. Use the meter in its rated range. 2. Connect it in series to measure the current.
Can a wattmeter that has a current through its current coil and a potential across its voltage indicate zero?
A: Only if the current is very small and the scaling very large. Like trying to measure micro amps on amp meter
What is the common use for a multimeter?
A multimeter is used to measure various properties of electricity. The "multi" refers to it multiple functions which can range from volt meter, current meter, resistance meter. The most common use would depend on the users preference to what is needed and measured most frequently.
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'.)
Why is it called multimeter?
since it stands for voltage ohm meter :) can measure voltage current and resistance

What Do Amps Measure?
You can measure the electrical current with an amp meter. Amperage measures the current flow.
How do you measure alternating current voltage and resistance?
You measure current by inserting an amp meter in series with the circuit or using a clamp-on meter to measure current by induction. You measure voltage with a volt meter across the supply. You measure resistance in ohms across the resistance. Luckily all these functions are in the same meter in most cases.
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.
When measuring current always place any type of meter in series with the circuit--is this true?
No. While it is true that one can measure current at any point in a circuit by breaking the circuit at that point and inserting the meter, not any meter will do it. One must use an ammeter to measure current.
Which instrument would measure an electric current?
A voltmeter or a multi-meter.
What instrument measures water velocity?
A device called a current meter is commonly used to measure water velocity. Current meters can be mechanical or electronic, and they work by directly measuring the speed at which water flows past a specific point in a river, stream, or other water body.
What is a meter to measure incoming signals called?
goniometer
Does a electric meter measure the number of protons in a current?
No, an electric meter measures the amount of electric charge passing through a circuit per unit time. The number of protons in a current is not relevant to the measurement of electricity by an electric meter.
What instrument is used by technicians for measuring current voltage and resistance?
The instrument is called a multi-meter. Multi part meaning that the meter has distinct functions. One setting can measure voltage, another function can measure resistance and the third function can measure a limited amount of current.The reason the current is limited is because the meter has to be connected in series to the circuit that it is measuring. There will be a maximum rating on the instrument stating the maximum amount of current allowed. Many times this is a DC current and it is not to be used for measuring AC current.For higher current measurements a clamp on ammeter should be used.
