| How many times is the maximum apparent power of the current source greater (or less) than the maximum useful power released across the resistance?
1) I = E / (r (ext) + R (n)) – Ohm’s law for a complete circuit.
2) P (max) = I ^ 2 * (r (ext) + R (n))
3) P (n) = I ^ 2 * R (n)
4) P (max) / P (n) = (r (ext) + R (n)) / R (n) = (1 + r (ext) / R (n))
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.
