voltage
Voltage- the measurement of electrical 'pressure'.
Voltage is a measurement of electrical force and amperage is a measurement of electrical flow. They are two different things altogether.
Ohms are the unit of measurement for electrical resistance. It indicates how much a material resists the flow of electric current.

The four main concepts of electricity are voltage (V), current (I), resistance (R), and power (P). Voltage is the electrical potential difference between two points, current is the flow of electric charge, resistance is the opposition to the flow of current, and power is the rate at which electrical energy is transferred.
The unit of measurement used by an ohm meter to quantify electrical resistance is ohms ().
The main unit of measurement for length is the meter (m).

The four main types of electrical injuries are: Electrical Shock: This occurs when an electrical current passes through the body, potentially affecting the heart and other organs. Burns: Electrical burns can result from contact with electrical sources, leading to severe tissue damage both at the entry and exit points of the current. Arc Burns: These occur when high-voltage electricity jumps from one conductor to another, causing burns without direct contact. Electrocution: This refers to fatal electrical injuries, typically resulting from high-voltage exposure that leads to death.
In a four-point probe measurement, the spacing between the probes should be equal and typically around 1 mm. This spacing ensures accurate measurement of the electrical properties of the sample being tested. Make sure the probes are evenly spaced and aligned with each other for reliable results.
The methods used for water resistivity measurement include the four-electrode method, the Wenner method, and the Schlumberger method. These methods involve passing an electrical current through the water and measuring the resistance to determine the resistivity of the water.
