What Are Voltage Transformers?
“Hi I’m Tim Gipson and I’m going to talk to you about voltage transformers. Voltage transformers are fairly common things that we will see around the house. I have one here and one of the most common ones is this is actually a charger for a cell phone and a typical thing for a voltage transformer is what it is doing is your house is wired with ac voltage which is 120 volts of electricity and ac stands for alternating current and that is typically what we find but we have a lot of devices that we use that actually run on direct current or dc power which is what you find in batteries and things like that. So what this transformer will do is it will take the ac electrical current and it converts it to a direct current so that you can either operate or charge something like a cell phone that runs on a battery and you’ll find several of these devices throughout your home. You’ll find them on telephone units so there is a particular one that has got a transformer that is plugged into a wall
