What are the 2 types of transformers?
Transformers generally have one of two types of cores: Core Type and Shell Type. These two types are distinguished from each other by the manner in which the primary and secondary coils are place around the steel core. Core type Transformers use a single, large coil to create electricity that is then used to power an entire transformer. This type of transformer is often used in larger, more powerful appliances or turbines. Shell type Transformers use two smaller coils to create electricity. These coils are placed around the steel core so that they can create more current and power an appliance or turbine more effectively. This type of transformer is often used in smaller devices, such as radios, cars, or home appliances.

What are the 3 types of power supply?
Linear power supplies are the simplest type of power supply and are used in most modern electronics. They consist of a power transformer that takes in AC electricity and turns it into voltages that your devices can use. Linear power supplies are often used in electronic devices that need to be powered by a steady, consistent voltage, such as computers, watches, and mobile phones. The downside to linear power supplies is that they can be quite expensive to build and maintain. They also require an external resistor to connect the positive (+) side of the transformer to the negative (-) side of the battery, which can be a bit of an added cost. switched power supplies are a newer type of regulated power supply and they have several advantages over linear power supplies. They first advantage is that they can be connected in any order you want them - this means you can use them in different devices or systems without having to worry about which one comes first. Secondly, switched supplies have on/off switches on them so you can easily control how much voltage is coming out of each individual device. This makes it much easier to troubleshoot problems with those pesky standby batteries or faulty contactors. Finally, battery-based regulators tend to
