List two typical uses of autotransformers.
What will be an ideal response?
On long single-phase and three-phase distribution lines where the line voltage must be increased to compensate for voltage drops in the line wires
In electronic circuits where several voltages are required
In three-phase manual and automatic motor starters to reduce the startup voltage applied to three-phase motors; the decreased voltage reduces the starting current surge
To provide a multivoltage source, as required by electronics laboratories
