What is the driving force that causes current to flow and what is it measured in?

Type your answer here... volts


When measuring current always place any type of meter in?

No. When measuring current, use an ammeter and place it in series in the circuit.


The current in a wire is determined by what?

an ammeter can be used to measure current flow, either direct insertion type, where the circuit must be opened and the meter is inserted in series with the load, or a clamp on type.


An electric current is the measure of what?

An electric current is a movement of charges, and it is measured in amperes or just amps. An ammeter is used to make this measurement. Current flow is a scalar quantity, and it refers to the number of charges passing a given point per unit of time.


How does the meter have to connect to the battery in order to provide an indication?

The meter ( as refered to a conventional moving coil analog pointer type ) basically operates on a Direct Current ( DC ) passing in its coils. Hence the meter inherently has a polarity of operation i.e the positive & negative inputs of the meter must be connected appropriately with the corresponding positive & negative potentials in the circuit being measured , so that the meter deflection is in the correct direction of the measuring scale ( typically clockwise movement ) Bsis Voltage & current measurement scales are linear , while resistance ohmic measurement scales are generally non linear. Incorrect polarity of connection will result in the meter deflecting in the opposite direction & usually will not damage the meter unless an inappropriate measuring range was selected. Whenever the magnitude of measured voltage or current is not known approximately beforehand, the best precaution is to use the highest range on the meter & stepping down the range if the deflection is too low for a good reading.This will prevent damage to the meter due to overload deflection which generally will damgage the delicate moving parts of the meter, which results in a total writeoff. For measuring voltages , the meter configuration as a voltmeter is used, where a series voltage dropping high value resistor appropriate to the range of voltage being measured is incorporated into the meter itself. The voltmeter is always connected across the points where the measurement is required. Hence no alteration of circuit is required for this measurement. For measuirng current, a low value resistor across the coils of the meter is incorporated appropriate to the range value of currents being measured, as a shunt to divert currents larger than what the basic meter can handle. It is necessary to break the circuit at a convinient point where the measurement is required and the meter inserted into the circuit. Hence an alteration of circuit is required for this measurement. When a meter is configured to measure resistance , a low voltage battery source with appropriate circuitry is incorporated into the meter itself to read the resistance value directly in ohms. Modern digital meters generally have bipolar measurement capabilities, in which the polarity of measurement is indicated. Here only the moving coil meter is replaced by a analog to digital convertor chip which directly displays the value on the digital readout. Otherwise the same measurement principles apply.

What meter reads amps and volts?

A volt-ampere meter. You can read current in two basic ways. The harder but more accurate way is to break the line where you are measuring current and basically insert the meter into the line so all current flows through the meter. The other type is a "clamp on" meter where the meter has something like a claw that you open and encircle the wire you want to measure. You determine the current by induction. The current flowing through the wire induces a smaller current in a loop created by the clamp on device. You can only measure current in one wire at a time. For example, you couldn't just clamp over a lamp cord and read a correct current because you are encircling two wires and the current going in each direction cancel each other out.

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.

What would the current be if you connected the meter to the wall outlet from the hot to the neutral using ohms law the meter to actually perform the test?

Your question is very confusing. When you say, 'meter', what type of meter? The only safe meter you can connect to a wall outlet is a voltmeter which will measure the actual voltage across the line and neutral (as opposed to the 'nominal' value). Then you bring in the subject of 'Ohm's Law' without explaining what you are trying to find. You need to rephrase the question so that it is clear what you are asking.
