From line-to-line (any two of the three leads) voltage or 'line voltage', the voltage is 208 V. The line-to-neutral (one of the three leads and the neutral conductor), or 'phase voltage', is 120 V.
Sounds more like you're trying to measure resistance...
Yes. If voltage leads the current, the impedance is inductive (this would be the case if the load is a motor). If current leads the voltage, the impedance is capacitive (this would be the case for a CFL light bulb).
This depends on your service voltage and whether you have any step down transformers in the building. The only way to know is to check yourself. Use a voltmeter or multimeter, with one lead on L1 terminal and one lead on Neutral terminal. Set the meter to read AC volts, with a range of at least 300 volts (your reading should either be 277 or 120.) The safest way to do this is to deenergize the circuit, place your leads, and then re-energize the circuit without touching anything. You should be able to get a reading without touching anything at all.
Simply set the multi meter on DC voltage, which is denoted by a line with dotted lines under it. Then place the red lead on the positive side of the bulb and the black lead on the negative side. If you do this incorrectly it will be a negative number but the same number if the leads are reversed. If you have a bad bulb the meter will show all zero´s. Otherwise you´ll get something like 0.01 which is a good indicator for a working bulb. The voltage across the light bulb will be the same voltage as the supply. Regardless of whether the bulb is good or bad the voltage potential will still be there. You are measuring voltage not amperage.
You can test a battery by using multimeter. Set the multimeter to the DC voltmeter setting and then place the leads of the multimeter across the leads of the battery. the multimeter will have a readout of the voltage.

Depends on the voltmeter. Some meters will display a positive voltage no matter how the leads are attached to the source. Others may indicate a negative voltage if leads are reversed.Another AnswerAn analogue voltmeter will always read downscale (i.e. 'backwards') if connected the wrong way around.Digital voltmeters generally indicate the correct voltage, but display a negative sign to indicate that the polarity is the wrong way around.Don't forget, when we say 'negative voltage', we are referring to its direction. Voltage, which is simply another word for 'potential difference', and it cannot be positive or negative in the sense of 'charge'.
The wire leads of the meter.

in series you XL, voltage leads the current, and in Parallel current leads the voltage. so your answer should reflect on this theory.
look at the multimeter! it has TWO LEADS touch them either side of the part you want to measure! wow I'm sure you could have answered that one yourself if you bothered to look at it!
generally voltmeters are connected in parallel in the circuit.If the voltmeter resistance is lower as it increases the current rating,because by connecting parallel we are decreasing the resistance,so if the voltmeter resistance is not too much higher it leads to burning of the meter,For that we can conclude that the in ideal the voltmeter has infinite resistance.
This is a middle school science level question. No offense, but if you don't know how to do this you should not be doing any electrical work, let alone commercial/industrial. If you are a homeowner, please buy a book. If you are a professional, please take a class and get licenced. Get a voltmeter. Set it on AC volts. Use the two leads to measure the voltage across the two points you are interested in.

The current leads the voltage by 90degree....
