Because the quantity it measures is 'EMF' or 'potential difference', that is,
the difference in potential between two points. There may be 1 or 1,000
circuit components between the two points.

If you charge four 50v capacitors in parallel then remove the 50v battery and hook it up to a volt meter will the meter say 50v or 200v?
If you charge four 50v capacitors in parallel then remove the 50v battery and hook them up to a volt meter the meter will indicate 50v.
How do you find voltage across capacitors in a serial parallel circuit?
Voltage across all parallel capacitor's is same i.e. it is equal to supply voltage, it can be measured using digital volt meter (any high input impedance volt meter). When capacitors are in series; voltage drop depends on charge stored in the capacitor. it can be given by the formula V x V = 2 / (joules x capacitance). This voltage can also be measured using digital volt meter.
How is a voltmeter wired in with the load?
An inline volt meter is designed to have the voltage pass through it. The wire has to be cut or otherwise disconnected, and the meter installed between the disconnected ends of the wiring.
How do you measure voltage?
Voltage can be measured using the difference between the potentiel between two ends of wire or by using a volt-meter. You can easily measure volt by volt or multimeter but remember voltage always measure across the components but in parallel
Why thermocouple voltmeter is connected across shunt resistance and electronic voltmeter across capacitor?
There is no such a thing as a thermocouple volt meter. A analogue or digital millivolt meter or volt meter is connected across a shunt or parallel with the shunt to measure the current through the resistor. Say the resistor value = 1 Ohm, then by using the Ohm law formula to calculate the current, say the voltage (voltage drop), read on the volt meter is 1.5 Volt that is R*V = A that is, 1Ω*1.5V = 1.5 Amp. Any type of DC volt meter, analogue or digital can be used to measure the voltage across a capacitor if the value of the capacitor is large enough that reading will be true RMS. as long as the supply current (EMF Power) are larger than the load current.
Volt meter is connected in what.?
Parallel
Placing a voltmeter into a circuit will raise the circuit resistance?
Usually a volt meter is placed across a component to measure the voltage drop across that component. Doing this places the volt meter resistance in parallel with that component's resistance, which will always lower the total resistance. Since the volt meter resistance is usually very large relative to the resistance of the element being measured, the total resistance does not change significantly. The formula for total resistance of two parallel elements is: Rtot = (R1*R2)/(R1+R2), as R1 (the volt meter) >> R2, Rtot ~= (R1*R2) / (R1) = R2 If a volt meter is placed into a circuit instead of around an element of that circuit, it will raise the resistance of the circuit, load the circuit with, and interrupt "normal" operation of the circuit (normal operation = how things would be without the meter in place). More importantly, the volt meter would then be measuring the voltage developped across itself (instead of an element of the circuit), which is not the point of this tool / this would be a misapplication of a volt meter.
How do you connect a volt meter to a car?
It depends on what you want to monitor. Most commonly the volt meter is connected in parallel with the battery or the alternator.

How do you connect volt meter in battery charger?
To measure voltage be in parallel with the battery. Series would measure current. Parallel measures potential.
Why volt meter are attached parallel to the circuit?
Because nothing has to pass through the meter. The voltmeter is only measuring the DIFFERENCE in electric potential between two points.
