(Part 02). 🎥 • HIGHER VOLTAGE - LOWER CURRENT, TRUE... ___________________________________________ 👇 Check out our content 👇 🔌 https://linktr.ee/Eletricity ___________________________________________ There is still a lot of doubt regarding the definition of proportionality between Current and electrical Voltage. This video tries to clarify in a very didactic way this doubt that some Electrical Professionals still have. If we look at the mathematical concepts that support these theories, we come to the conclusion that voltage and electric current are directly proportional when applied to purely resistive loads or loads called passive. In the case of active loads such as full-range switching power supplies, due to an internal electronic system that corrects the relationship between voltage and current in order to maintain constant working power in the equipment, in this type of case the relationship between voltage and current is inversely proportional within the working voltage range of these sources, which are normally 90-240V. But what about transformers: Why do I have a much thinner cable in the primary than in the secondary? Why is the current in the primary much lower than in the secondary? The main rule that needs to be kept in mind is that in transformers the power of the primary will always be equal to the power of the secondary (in real situations there is an internal loss in the transformer of part of this power that in our case can be disregarded). When transformers supply resistive loads, the behavior of voltages and currents are the same: the higher the voltage, the higher the electric current, and this applies to both the primary and secondary of the transformer. Ohm's law, which relates the behavior of voltage and current in resistive loads as being directly proportional, remains valid. Looking at the secondary side of the transformer, I will see a decrease in voltage along with a decrease in current. Looking at the primary side of the transformer, the same thing happens: current and voltage decrease proportionally. Now, if I were to relate the primary current to the secondary current, in this case, due to the transformer's characteristic of maintaining constant power in both the primary and secondary, then for the same load, the higher the voltage applied to the primary of my transformer, the lower the value of the electric current in the primary of this transformer will be. Analyzing the primary in isolation from the secondary, the relationship that the higher the voltage, the greater the current will always be valid in the case of supplying resistive loads. And the same concept will be repeated when we analyze the secondary in isolation. Using the term: “the higher the voltage, the lower the current” does not apply to all cases and you may be being misled into interpreting electrical concepts.
