Question
Which of the following is the SI unit of electric charge
and is equivalent to the charge contained in nearly 6 × 1018 electrons?Solution
A coulomb (C) is the standard unit of electric charge in the International System of Units (SI). It is the amount of electricity that a 1-ampere (A) current carries in one second (s). A quantity of 1 C is equal to the electrical charge of approximately 6.24 x 1018 electrons or protons.
