For example, many cell phones, laptops, video games, and power tools and small appliances have a transformer built into their plug-in unit (like that in Figure \(\PageIndex{1}\)) that changes 120 V or 240 V AC into whatever voltage the device uses.
Example 8-2: 300 kVA 2400-120, 60 Hz single phase transformer operates at 2300 volts on the primary side. It supplies 115 kVA to a load that has a power factor of 0.723 lagging. Assume idea operation and find: a.) secondary voltage at operating voltage b.) secondary current c.) impedance of the load as seen on the secondary side
Split-phase Power System. Instead of a single 240-volt power supply, we use two 120 volt supplies (in phase with each other!) in series to produce 240 volts, then run a third wire to the connection point between the loads to handle the eventuality of one load opening. This is called a split-phase power system.

30 Αυγ 2017 · The two ends or the transformer winding (120 V A and 120 V B) are each 120 Volts from Neutral, but 180 degrees out-of-phase, so you get 240 volts between them. Most outlets in a home will connect between 120 V A and Neutral, or between 120 V B and neutral, so will get 120 volts.
