Which conductor is said to be at
a. lower potential
b. higher potential?
a. In a neutral conductor, the number of protons and electrons is equal in number. The conductor having an excess of electrons is negatively charged and said to be at a lower potential.
Hence, the conductor having an excess of electrons is said to be at a lower potential.
b. The conductor having a deficiency of electrons is positively charged and said to be at a higher potential.
Hence, the conductor having a deficiency of electrons is said to be at higher potential.
