A device made of two coils, which converts current of one voltage into current of another voltage. In a step-up transformer, the primary coil has fewer turns than the secondary, thus increasing the voltage.

An electronic component which changes one voltage to another using the principle of inductance. A transformer is comprised of two coils of wire, one coil having a different number of windings from the second. The first coil converts electricity into a magnetic field, and the second converts a magnetic field into electricity. If the input voltage has more windings, the output voltage will be lower and have a higher amperage. If the input voltage has fewer windings, the output voltage will be higher and have a lower amperage. Transformers are not efficient devices, and some electricity is lost.

An electrical device consisting of a magnet with wires coming in and would around it on one side, then another set of wires wound around it on the other side. It allows isolation of one side to the other since the wires are not actually touching each other but it still allows (alternating) electrical current to pass. Depending on the ratio of the number of times the two different wires are wound around the magnets, it will also change the amount of voltage/wattage passed through it such tas changing a micrjophone level signal to a line level signal. Power transformers step-up or step-down electricity that's then used to power other electrical devices at a different voltage.

An electrical device that transfers energy from one circuit to another purely by magnetic coupling. People often wonder what kind of transformer they need; a basic guideline is that the maximum number of lights that can be connected is determined by the total wattage of all the fixtures attached to the transformer system. If the transformer is 100-watt, the total wattage must not exceed 100 watts. For example if you had 10 garden lights with 10-watt bulbs, you would need a 100 watt transformer. Do not exceed the maximum wattage capacity, if your total wattage is too high, divide the load between two transformers or look for a more powerful transformer.

An electromagnetic device for changing the voltage of alternating current electricity. Every transformer has a primary coil and one or more secondary coils. The primary coil receives electrical energy from a power source and couples this energy to the secondary coils by means of a changing magnetic field. The energy appears as an electromagnetic force across the coil, and if a load is connected to the secondary the energy is transferred to the load. The voltage at which electric power is used in motors and lamps is less than that required for distribution. It is necessary to raise the voltage at the generating station to the value required for transmission, which is called "step up" the voltage. Then to lower it at the point of consumption to the values required by the motors and lamps, which is called "step down". The transformer is what makes these changes in voltage.
