**Introduction**
The charge of an electron is a fundamental constant in physics and is denoted by the symbol "e". The accepted value of the charge of an electron is 1.6 × 10^-19 Coulombs. However, it is important to understand why we write the charge of an electron as a positive value rather than a negative value. In this explanation, we will delve into the historical context and the convention established in the field of physics.

**Historical Background**
In the early 20th century, during the discovery and understanding of the structure of the atom, physicists realized that atoms contain negatively charged particles called electrons. At that time, the convention was to consider the charge of protons as positive and the charge of electrons as negative. This convention was based on the observation that when objects were rubbed together, one acquired a positive charge and the other acquired a negative charge.

**Charge and Conservation**
One of the fundamental principles of physics is the conservation of charge. This principle states that the total charge of an isolated system remains constant over time. In other words, charge cannot be created or destroyed, only transferred or redistributed. This principle is consistent with the observation that in chemical reactions and electrical circuits, the total charge before and after remains the same.

**The Electron Charge Convention**
The convention of assigning a positive value to the charge of an electron is rooted in the concept of conservation of charge. By assigning a positive value to the charge of an electron, we maintain the overall charge neutrality of the system.

**Mathematical Consistency**
Writing the charge of an electron as a positive value allows for mathematical consistency in equations and calculations involving charge. In many physical equations, the charge of an electron is multiplied by its quantity, resulting in a negative value. If we initially assigned a negative value to the charge of an electron, the mathematical manipulations and interpretations of equations would become cumbersome and confusing.

**Conclusion**
In conclusion, we write the charge of an electron as 1.6 × 10^-19 rather than -1.6 × 10^-19 to maintain consistency with the convention established in the field of physics. This convention is rooted in the historical understanding of charges, the principle of conservation of charge, and the mathematical consistency it provides. By adopting this convention, we ensure clarity and ease of interpretation in various physical equations and calculations involving the charge of an electron.
