Question

How is a charged of a body measured?

Answer 1

Charge is measured in Coulombs (C), which represent 6.242×1018 e, where e is the charge of a proton. Charges can be positive or negative, and as such a singular proton has a charge of 1.602×10−19 C, while an electron has a charge of -1.602×10−19 C. Electric charge, like mass, is conserved.

Answer 2

The charge of a body is measured with the help of an electroscope.

• A scientific instrument called the electroscope, helps to determine the immensity or magnitude and the presence of electric charge on a body.
• Electric charge can either be negative or positive depending on electrons and protons respectively.
• Subatomic particles carry electric charges.
• If a body has an electric charge then it is easily detected and then measured by an electroscope that is uncharged.
