Hello everyone,
I need some help with transformers as I am very confused...
I understand the role of a step up transformer - the secondary coil has more turns thus has a higher voltage induced. This in turn reduces the current and the overall heating effect is reduced. This is why transmission lines have such high voltages i.e so that they do not melt.
So, when I connect a lamp to a step-up secondary coil the lamp gets brighter. I understand it so that if voltage increases then current DECREASES as with transmission lines. So why does it get brighter - what am I missing?
Thanks for any help!
