Why measure voltage with a meter and not just take it as 12V from the power pack?
Wiki User
∙ 15y ago
The power pack has internal resistance of its own, equal to r. The voltage across the load resistance R is therefore: VR = 12(R / R + r) Thus the P.D. (VR) varies according to the load resistance R; it is impossible to ascribe an absolute value to it.

What is used to check for line voltage sags?
just a digital voltage meter measure at the origin, and then at the end of line
How do you test a cars power polarity?
by using a Digital Multi meter just check the voltage and it will also give you the sign with the voltage value
Can you measure a length in the world with just one meter stick?
yes you can if you know how to measure things with meter sticks
How do you meter a 208v load meter only 1 phase add the two?
The voltage 208 is a three phase voltage. Single phase is classed as the voltage obtained from any two legs of the three phase voltage system. The voltage between L1 to L2 = 208. L2 to L3 = 208 volts and L3 to L1 = 208 volts. To measure the load of the 208 volt device just clamp an amp meter around one of the legs coming from the load. This will give you the amperage that the load draws.
An ammeter and voltage range are measure the current and voltage electric lamp if mistake meter interchange what will happen?
1. Voltmeter has high impedance and hence will restrict the current severely.a) Electric Bulb will not glowb) The Ammeter will just measure the current that Voltmeter allows and since this current is much smaller than actual current nothing will happen to ammeter.c) The Voltmeter will measure the Voltage that is being applied.d) This will allow you to measure the resistance of the Voltmeter.VR=V/I
Is a meter 10 to the 1st power?
No. 10 to the first power is a number: a pure number. It is not a measure of length, nor mass, nor area, nor energy. Just a number.
How do you measure the reflected voltage?
Assuming you mean the reflected voltage in a transmission line (such as coaxial cable) where the cable, source and load must all have the same impedance for maximum power transfer to the load. If the impedances are not matched, some power is reflected from the load back to the source.In simple cases, this wastes power, in serious cases the source (a radio/radar transmitter) will suffer serious damage or just plain blow up (!)You need either a reflectometer or a standing-wave ratio meter (SWR meter).The SWR meter is simplest. You just connect it "in line" between the source and load.You switch the meter to measure the forward (to the load) voltage, then switch to measure the reverse (from the load) voltage.An ideal SWR reading is 1:1, showing perfect matching.This doesn't mean the two voltages (forward and reverse) are equal (that would imply the power is all being returned!).A 1:1 ratio shows that there are no peaks or nodes(collisions between forward and reverse voltages) and that the voltage distribution along the line is "flat". This shows perfect matching.For a more complete description, check out any of the Amateur Radio websites online - hams spend a lot of time getting transmitters, feedlines and antennas matched up.
Can RF be measured using VTVMs?
Of course. For a long time, that was the only way to measure an RF voltage. You just have to be careful how you set up your instrument ... grounding & bypassing etc. ... so that you and your meter don't just become an antenna, and so that you don't detune the RF source when you couple your meter to it.
How i can measure sound frequency from sound level meter?
You just need a meter that measure Hertz (high and low) as well as db (volume)
What unit of electricity measures is used to measure the power consumption of a device?
The kilowatt hour (KWHr) measures electricity use.
How do you use an analog multimeter to measure voltage?
Just set to AC or DC volts and probe the two points you wish to measure voltage across.
What would happen if ammeter were connected directly across a voltage source?
An ammeter measures current by either being inserted in series with the load being measured or using a clamp-on device that induces a proportional current that the meter measures. Nothing should happen if you connect an ammeter across a voltage source unless it was very high voltage compared to the rating of the meter.
