In this circuit it’s nought point two three amps. And a voltmeter measures the potential difference in volts, which is the difference in energy between two parts of a circuit. Across the cell ...
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 ...
