How long will 1 watt last?

The watt-hour, which is symbolized Wh, is a unit of energy equivalent to one watt of power expended for one hour of time.

How much energy is 1 watt?

Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it's running. So a 60W bulb is burning 60 Joules of energy every second you have it turned on.

What does 1 watt-hour mean?

It's the equivalent of the total energy supplied if electrical power of one watt is maintained for one hour; that's equal to 3600 joules.

How long will a watt battery last?

Watt itself is defined as Ampere X Voltage. So if a 5 Volt battery has 20 Watt Hour rating, and, it draws 2 Amp current, then the Watt delivered by Battery = 10 Watts ( 5 Volts x 2 Ampere). The battery will last 2 hours.

How long is 10 watt-hours?
