Electric Field Calculator
An electric field is a field that exerts a force on charges – attracting or repelling them. Moreover, every single charge generates its own electric field. That's why, for example, two electrons with the elementary charge e = 1.6 × 1 0 − 19 C e = 1.6 times 10^{-19} text{C} e = 1.6 × 1 0 − 19 C repel each other.
