Net Charge Calculator:
Enter the values of number of excess charges, n and charge of a single electron, e(C) to determine the value of Net charge, Q(C).
Net Charge:
The net charge (Q) is the total charge accumulated or transferred in a system. It is measured in Coulombs (C). The net charge is the product of the number of electrons (n) involved in the transfer and the elementary charge (e), which is the charge of a single electron.
The elementary charge (e) is approximately 1.6 * 10-19C. The net charge can be either positive or negative, depending on whether electrons are being removed or added.Net charge plays a key role in determining the electrical properties of materials and in understanding electrostatic interactions.
In basic terms, a net charge is formed when there is an unequal number of protons and electrons in a system. The net charge of an object determines how it interacts with electric fields and other charged objects.
Net charge, Q(C) in Coulombs equals the number of excess charges, n multiplied by the charge of a single electron, e(C) in Coulombs.
Net charge, Q(C)= n * e(C)
Q(C)= net charge in Coulombs, C.
n = number of excess charge.
e(C) = charge of a single electron in Coulombs, C (1.6 * 10-19 C).
Net Charge Calculation:
- An object has an excess of 5 * 1018 electrons. Calculate its net charge.
Given: n = 5 * 1018, e(C) = 1.6 * 10-19 C.
Net charge, Q(C)= n * e(C)
Q(C)= 5 * 1018 *1.6 * 10-19
Q(C)= 0.8C.
- An object carries a net charge of -3.2 C. Calculate the number of excess electrons.
Given: Q(C)= -3.2C, e(C) = 1.6 * 10-19 C.
Net charge, Q(C)= n * e(C)
n = Q(C)/ e(C)
n = -3.2 / 1.6 * 10-19
n = -2* 1019(The object has 2 × 10¹⁹ excess electrons).
