Electric field strength is a quantitative expression of the intensity of an electric field at a particular location. The standard unit is the volt per meter (v/m or v · m -1 ). A field strength of 1 v/m represents a potential difference of one volt between points separated by one meter. From: whatis.techtarget.com

∙ 15y agoA voltmeter works by adding a parallel branch with high impedence across two points. Based on the amount of current (measured by electronic components within the meter) that flows through the parallel branch, and the known resistance of that branch, the voltage can be calculated via Ohm's Law.
The idea is to have the impedance be very high compared to the two points, so that the amount of current running through the meter will be very small compared to the current between the two points.

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 know your homemade windmill is generating 120v?
Purchase, borrow, or have someone with a volt meter or multimeter check it for you. If you don't know what a volt meter or multi meter is, have an electrician check it for you.
