An ammeter measures amperage not voltage.
You have to measure the voltage, and the current. The resistance is then calculated by using Ohm's Law.
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
You can measure high voltage by using Potential Transformer (PT). or by using utility meter or power manager. ANSWER: Adding a hi resistance in series with a low resistance and measuring that voltage drop. If the resistance is known then current is determined and the source can be calculated. transformers do not work well with DC,
You measure current by inserting an amp meter in series with the circuit or using a clamp-on meter to measure current by induction. You measure voltage with a volt meter across the supply. You measure resistance in ohms across the resistance. Luckily all these functions are in the same meter in most cases.
You measure the peak to peak voltage and divide by 2.
Any one using a voltage test instrument can measure charge differential voltage.
An ammeter measures amperage not voltage.
You measure voltage using a voltmeter which involves measuring the electrical potential difference between 2 points in an electrical circuit.
Use a voltmeter with a high input impedance and measure at the source the voltage.

Using very sensitive accelerometers.
only earthing can not be measure. Anyone can only measures the voltage and the current with respect to the earthing .Thus it is impossible to measure the earthing.

A standard oscilloscope is designed to measure voltage, you need a current probe for your oscilloscope to measure current.
