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 circuit is equal to the supply voltage, \({V_s}\).

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 ...

For cases like that, it is tempting to use some voltage multiplication scheme. There are many, but for this post, I’m going to take you inside a Dickson charge pump. This is Circuit VR because ...

In other words, with the perfect setup, you could put a digital panel meter that reads the voltage in the circuit, and read the resistance directly. Zeroing it out would require more effort to get ...
