What is voltage and current how to measure it, size of cable ,

Question

Accepted Answer

Voltage is the electrical potential difference between two points, measured in volts. Current is the flow of electric charge, measured in amperes.

Voltage is the electrical potential difference between two points, measured in volts. It is typically measured using a voltmeter.
Current is the flow of electric charge, measured in amperes. It is typically measured using an ammeter.
The size of a cable is determined by its current-carrying capacity, which is influenced by factors such as the material, insulation, and cross-sectional area of the cable.
The size of a cable is often specified in terms of its gauge or cross-sectional area, with larger gauge numbers indicating smaller cable sizes.
For example, a 12-gauge cable has a larger cross-sectional area and can carry more current than a 16-gauge cable.
