True or False: Lap winding coils are built with small diameter wires.

Lap winding coils are typically constructed using larger diameter wires. This is because lap winding is often utilized in applications where higher current capacity and lower resistance are required, making the use of thicker wires more advantageous. The thicker wire enables the coil to handle more electricity without overheating, which is essential for efficient operation in many electrical machines, such as motors and generators. In contrast, smaller diameter wires might be used in different winding types, such as wave winding, but that's not characteristic of lap winding. Therefore, stating that lap winding coils are constructed with small diameter wires is inaccurate, leading to the conclusion that the answer is indeed that this statement is false.
