Question

The charge on a body is +1 C. Find the number of electrons in excess or deficit on the body.

• A. 6.25 $\times {10}^1$ electrons
• B. 6.25 $\times {10}^{-18}$ electrons
• C. 6.25 $\times {10}^{-1}$ electrons
• D. 6.25 $\times {10}^{18}$ electrons

Answer 1

The correct option is D 6.25 $\times {10}^{18}$ electrons

The SI unit of electric charge is Coulomb, One coulomb is equal to about $6.242\times {10}^{18}e$.
One coulomb is defined as the quantity of charge which will pass through the cross section of an electrical conductor while one ampere current is flowing through the conductor in one second. Electric charge is denoted by Q.
