Where do you place the leads to measure the single phase voltage of a three phase power source?
- In delta wiring measure between any two phases.
- In wye wiring measure between any phase and neutral.
Do you know whether you have delta or wye wiring?
CommentThe above answer should read 'between any two lines' and 'between any line and neutral'. There is no such thing as a 'phase' conductor!

What is the maximum voltage that the VOM can measure?
Mine can measure 1000 volts. After that special insulated test leads are needed to protect the operator.
Does it matter if the voltage leads the current or the current leads the voltage?
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).
How to measure voltage drop accurately and effectively?
To measure voltage drop accurately and effectively, use a multimeter set to the voltage setting. Connect the multimeter leads across the component or circuit being tested. Ensure a good connection and check for any resistance in the circuit. Record the voltage reading displayed on the multimeter.
HOW TO MEASURE RIPPLE AC VOLTAGE?
To measure ripple AC voltage, use an oscilloscope or a true RMS multimeter. Connect the oscilloscope probes across the output where the ripple voltage is present, ensuring proper grounding. Set the oscilloscope to an appropriate time base to visualize the waveform, and measure the peak-to-peak voltage to determine the ripple magnitude. For a multimeter, select the AC voltage setting and connect the leads across the same output to get a reading of the ripple voltage.
How do you repair the stereo on a 2001 Stratus if it does not light up and CDs do not play but the fuses are okay?
Pull the radio and make sure all the connectors are still connected to the radio, second try to determine which leads are power and ground and measure voltage on the leads coming to the radio, if you have voltage and it still will not power up after reconnecting, then consider replacing the unit if no voltage exist follow that backward toward the power source. Make sure key is in the correct position to have power available at the radio.
What voltage should 208 3 phase leads read?
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.
Why is the voltage reading always a minus figure when using a digital multimeter to measure the DC voltage from the output jacks of a cassette deck?
I would imagine that reversing the leads would rectify that. (No pun intended.)
When you measure voltage with a voltmeter you must break open the circuit and connect the meters test leads in series with the other circuit components?
Sounds more like you're trying to measure resistance...
What determine the polarity of the voltage across a resistor?
A: Current flow only one way form positive to a less positive point. However it is possible to measure negative and positive voltage drop it the meter leads are reversed.
How do you connect a voltmeter to a computer to measure the voltage?
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!
How would you measure a relays contacts resistance?
The voltage drop across a relay coil will be the same as the coil supply voltage. If you are trying to see if the coil is good or not, remove one of the voltage supply leads and check for continuity by using an ohm meter across the coil leads. A reading will tell you that the coil is intact and not open.
What happens to current flow in a capacitive circuit in comparison to voltage?
The current leads the voltage by 90degree....
