Summer Camp. Santa Cruz County Summer Camp. Location: Camp Loma. 2017 Summer Camp. Available to Santa Cruz and San Benito County Members. 4-H Summer camp gives youth a chance to explore the outdoors, meet new friends, try new things, and create memories they will remember for a lifetime.
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. A varying current in one coil of the transformer produces a varying magnetic field, which in turn induces a voltage in a second coil. Power can be transferred between the two coils through the magnetic field, without a metallic connection between the two circuits.
The two coils are referred to as the primary coil and the secondary coil. The basic function of the transformer is to convert the incoming power to a different output power. Basically, it pumps up the voltage that goes out of the transformer.To do so, a varying current will go through the primary coil and create a varying magnetic flux in the core.ach transformer is based on two principles. The first is that an electric current runs through the primary coil to create the necessary magnetic field. The second is that a varying magnetic field exists in the secondary coil, which creates a voltage across the ends of that coil.
