What is the equivalent of 1 watt?

The equivalent of 1 watt is defined as the rate at which energy is transferred or converted when 1 joule of energy is used in 1 second. This fundamental relationship means that when a device operates at 1 watt, it is doing work or transferring energy at that rate consistently over time.

In practical terms, if you have an electrical appliance that consumes 1 watt of power, it draws 1 joule of energy each second it operates. This definition is essential in understanding power in physics, particularly in the context of electrical systems, mechanics, and energy transfer.

The other options involve different units or definitions. For example, newtons relate to force, not directly to power or energy, while joule per minute does not fit the instantaneous rate measurement (it would measure power in joules per minute, not joules per second). Watt-hours measure energy over time rather than power, which further distinguishes it from the definition of a watt.
