What do watts measure regarding electrical devices?

Watts measure the amount of electricity used when operating a device. In electrical terms, one watt is defined as one joule per second and represents the rate at which energy is consumed or converted. When an electrical device is in operation, watts indicate how much electrical power it is using at that moment, which directly relates to its consumption of electricity. This measurement helps in determining operating costs and energy efficiency.

Understanding watts is fundamental for professionals working with electrical devices, especially in contexts like structural drying where various equipment consumes power. This knowledge aids in planning electrical requirements and managing energy use effectively during operations.
