Let us recall the formula given to us in the physics textbook of the 10th grade of the basic course for a complete circuit:
I = E (epsilon) / R + r
E = I * (R + r) = 2.5 * 12.5 = 31.25V

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
