A step-up transformer is a type of electrical transformer that increases the voltage from the primary winding to the secondary winding while reducing the current. This device operates on the principle of electromagnetic induction, where alternating current in the primary coil induces a magnetic field that creates a higher voltage in the secondary coil due to the ratio of turns in the windings. The ability to raise voltage makes step-up transformers essential in power distribution systems, allowing electricity to travel longer distances with reduced losses.
