Answer "With a volt meter." That last answer could be improved a bit as measured by my dolt meter. One uses a volt meter to measure a 220 outlet by setting it to '…Voltage' or a symbol that looks like a 'V' with a tilde over or beside it for AC. Set the voltage range to 200 or 600 or something close. Put one lead in a socket on the volt meter that probably says 'COM', and put the other in the 'V' socket on the meter. You should read zeroes whether the leads are touching or not. There will be (probably) 3 or 4 outlet socket holes. If 3, two will look slanted and the third will either be straight or have an 'L' shape to it. The L or straight socket is your ground/common socket. The two slanted sockets are your hot sockets. Putting a lead in each of the slanted sockets (being careful to hold the leads by the non-metalic part) should yield your reading, about 220-240.
Place a voltmeter across the two points in the circuit you want to measure, and measure it. Be sure to know the expected voltage so that you can take appropriate safety precau…tions, and know the impedance of the circuit so that you can choose a voltmeter with a high enough internal impedance that it will not significantly affect the circuit.
Use a voltmeter
A voltmeter uses the principle of Ohm's law, which states simply that the amount of current that flows in a circuit is equal to the voltage applied divided by the resistance o…f the circuit. Therefore, if one were to connect a known resistance in series with a meter across a voltage source, then the meter deflection would be proportional to the current flow and hence the voltage. The meter is calibrated in volts so that the test voltage can be read directly. The meter used in a voltmeter is very sensitive, typically 50 micro-amperes so that it does not affect the reading by its load on the circuit. pizza is good when volts don't go thru!!
Add a voltmeter to one of the lines in parallel.
There must be current flow through the circuit to measure any voltage
dude this is heavy... if you add the ........
The only reliable method of obtaining reasonably accurate voltage and current measurements is to use meters designed for the purpose and maintained in reasonably good cond…ition. For the best accuracy, the test equipment ... even the lowliest multimeter ... is calibrated periodically against traceable standards.
frist off all calculate current through that resistance then use ohms law and remember one thing resistance connected parallel acros Voltage source. A voltmeter is used to mea…sure voltage. To calculate the voltage across a resistor you must first know the current through it, and then use Ohm's law. Ohm's law states that voltage = current x resistance.
You place the volt meter in parallel with the parallel circuit.
You simply place a voltmeter across the load. That will give you voltage drop. Just be careful to use the correct voltmeter and take appropriate safety precautions to prevent… electrocution and/or damage. Also, note that placing a meter across a load might elevate the ground lead potential on the meter, so you do not want to have the meter grounded in any way.
You can measure the potential difference between the two line conductors (L1 and L2), or the potential difference between either line conductor and the neutral conductor (N).
First of all, there is no such thing as 'phase to earth'; the correct term is 'line to earth'. This can be done by connecting a voltmeter between the line conductor and an ear…thed exposed metal part.
An ammeter measures amperage not voltage.
It is measured using a Voltmeter
