transformers -- Don't understand VpIp = VsIs
If the equation below of any transformer is true, therefore it does not matter if i connect a lightbulb or anything else either to the primary or the secundary, it should be working the same, right? I have a 220v-3v step down transformer and i can connect an led without burning it. How is that possible? Do we lose power here? Shouldn't be the current much higher in the secondary?
