The voltmeter is connected in parallel with the component. The supply voltage is shared between components in a series circuit, so the sum of the voltages across all of the components in a series ...

It’s called a circuit. For example ... a component can be measured by connecting the leads of the voltmeter on each side of the component. The diagram below shows how a voltmeter can be ...

The device works using a very low-impedance resonant circuit and a very high-impedance voltmeter. It measures the ratio of the voltage across the known circuit and the unknown circuit. This ...
