why a transformer is an AC device and not a DC device
A phone charger is a common use of a transformer.
Explain why a transformer is an AC device and not a DC device. If the voltage of the wall outlet is 120 v and the output of the transformer is 3 v, is this a step-up or a step-down transformer? Describe whether the current is higher on the wall side or the phone side of this device.
Ok I’m pretty sure these are just your homewok questions, you must have been taught this stuff at some point. Read over your notes or check your text book, and if you still have problem then ask questions about the points you don’t quite understand, not just the whole question.
This type of transformer, aka power adaptor, is a step-down transformer. You’re taking 120V and bringing it down to 3V. And the reason why it’s an AC device, not DC, is because with alternating current going through the primary coil of the transformer, a electromagnetic field can be achieved…this cannot be done with direct current. The electromagnetic field excites the secondary coil, thus creating a voltage.
How in the Hell can you Assume that b1ff - Now I’ll bet most of the Pretty ladies in this sight ALL want to know about Electricity. Fact is Im surprised there are not more threads. So step back Man. Dang I still dont know how you established that.
Electricity is Fun For everyone. Just remember to BE Safe with it. Always try to Unplug appliances and Female toys the Right way. Because if you dont some of the Electricity will Spill out on the Carpet !!
