Volt.<\/strong> The SI unit of potential difference is the volt (V), named after the Italian scientist Alessandro Volta, who invented the electric battery. The potential difference, commonly known as voltage, is a crucial concept in electricity and electronics. It refers to the difference in electric potential between two points in a circuit, which causes an electric current to flow.<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>Complete Explanation<\/strong><\/p>\n\n\n\n<p>Potential Difference is the work done to move a unit charge from one point to another in an electric circuit. It is measured in volts (V) and determines the strength of an electric source, like a battery or power supply. Potential difference is mathematically defined as:<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/lh7-rt.googleusercontent.com\/docsz\/AD_4nXfWzopq_j_7iz-MXQeW01QIlt4VksYHL2uCQL8QBTiKKOGTrsaz9WWZcvv3-xIH7kWNr4O6ZPUjiFDQmhkWmncGjwfgbyJzigwRIxxOtM5knIBGEYpvtzUet3yu3DztiZ0Y4obHtg?key=0pVj-FIzeTFNnI5AuYMfqRqw\" alt=\"Potential difference formula\" \/><\/figure>\n\n\n\n<p>Where:<\/p>\n\n\n\n<p><strong>V<\/strong> = Potential difference (volt)<br><strong>W<\/strong> = Work done (joule)<br><strong>Q<\/strong> = Charge (coulomb)<\/p>\n\n\n\n<p>This means that 1 volt is the potential difference when 1 joule of work is done to move 1 coulomb of charge.<\/p>\n\n\n\n<p><strong>Why Are the Other Options Incorrect?<\/strong><\/p>\n\n\n\n<p><strong>A.
