Why is there always voltage shown on my voltmeter even though its not connected too anything?
If your test meter is an analog type of meter there should be a zeroing screw on the meter face that is connected to the needle movement. Turn this screw to zero the meter. If the meter is a digital there should be a potentiometer, probably in the battery compartment that can be used to zero the display.
What else can I help you with?
To measure voltage drop across a component or connector the voltmeter must be connected in?
it must be connected in parallel as always
Why always voltmeter is connected in parallel with load terminals?
A voltmeter is connected in parallel with load terminals because it is designed to measure the voltage across those terminals without significantly affecting the circuit. When connected in parallel, it can accurately capture the potential difference across the load while maintaining its high internal resistance, which minimizes the current drawn from the circuit. This ensures that the measurement reflects the actual voltage present across the load, allowing for precise voltage readings.
How do you connect a voltmeter?
You can get one in a lot of places. Some places are Sears, Home Depot, Maybe Radio Shack, or some other hardware store. The best brand you can get is Fluke. It is pretty expensive but it is really accurate.
Why the series resistor of the voltmeter is high?
Aim of any measuring instrument is to measure the object without affecting it. Voltmeter is used to measure voltage between two points and connected in parallel. Thus voltmeter should not change the voltage. If voltmeter resistance is very high, it will be as good as infinity compared to load. Thus connecting voltmeter will not change the voltage and measure it accurately.
Is Voltmeter Scale showing Volts with wavy line DC?
A voltmeter scale showing a wavy line typically indicates an alternating current (AC) voltage rather than direct current (DC). In AC measurements, the wavy line represents the sinusoidal nature of the voltage over time. If the voltmeter is intended to measure DC voltage, it should display a steady value without any fluctuations. Always check the voltmeter's settings to ensure it is used correctly for the type of current being measured.

Should a Voltmeter always be connected in a series with a component?
Voltmeter should be connected always in parallel to a circuit ANSWER : IT should be in parallel except when used to measure current. Then it should be placed in series across a shunt.
What is the voltage in a circuit?
zero That's not always true. If you have a 12 volt battery not connected to anything and you measure the terminal voltage, it will be 12 volts.

What is the difference between ammeters and amp meters?
An Ammeter connects a low impedance on the test points, so the equivalent of that is a "short circuit" between the test points. This is done to avoid a drop of current on the tested circuit. A Voltmeter connects a high impedance on the test points, so the equivalent of that is a "open circuit" between the test points. This is done to avoid a drop of voltage on the tested circuit. --------- In terms of external connections Ammeter (used to measure current) is connected in series of the circuit (through which the current flow need to be measured) and voltmeter (used to measure voltage) is connected in parallel to points in circuit (across which voltage needs to be measured).
What path will the current takes in a series circuit with a voltmeter pause does the current goes through voltmeter pause because if it does pause isn't current suppose to be taking the shortest path?
A voltmeter is designed to operate like a very large resistor (order of megaOhms), in parallel to the circuit that it is measuring. As long as the voltmeter resistance is much larger than the circuit that it is measuring, it will draw very little current away from the circuit and will only minimally disturb the operating circuit. See related link. If the voltmeter is connected in series with the rest of the circuit, then that is the same as connecting a very large resistor in series.So for example if you have 10 volt battery and a 10 ohm resistor, that would be 1 amp (without the voltmeter). Now if the voltmeter is 10 megaohm, the total resistance is 10000010 ohms, so the current is 0.999999 microamperes, and the voltage across the 10 ohm resistor is 9.99999 microvolts, while the voltage across the voltmeter is 9.999990 Volts (these numbers are rounded, but you get the idea).Suppose you put in series with a 1 kiloOhm (not sure about that spelling) resistor. The total resistance is 10001000 ohms, and current is 0.99990 microamperes, the voltage across resistor is now 0.9999 millivolts (it was microvolts) and the voltage across the voltmeter is 9.9990001 volts
What will happen when the terminal of the volmeter are inversed and used to read the voltage of the DC supply?
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'.
