How to calculate electric flux<br>Know the formula for electric flux. [substeps] The electric flux through a surface a is equal to the dot product of the electric field and area vectors e and a. the dot product of two vectors is equal to the product of their respective magnitudes multiplied by the cosine of the angle between them. Determine the magnitude and direction of your electric field vector.
