North Dakota Barber Practice Exam

A higher watt bulb would provide too much heat and could increase the risk of injury to clients, while a lower watt bulb may not provide enough light for proper precision during manicures. Therefore, option A, with a lower wattage of 40, strikes the necessary balance between providing enough light and not causing potential safety hazards. Options B, C, and D, with higher wattages of 60, 75, and 100 respectively, may be too bright and may create an uncomfortable and potentially unsafe environment for both the client and the manicurist. Therefore, A is the most appropriate choice for a wattage in an adjustable lamp on a manicuring table.
