# What is a watt?

The watt is a unit of power . It is a Newton meter persecond, or can be given as a joule per second. We often encounterit in electrical calculations, and it is the unit of po…wer forapplications there. The formula for power is given here: P = I x E In this expression, the power (P) in watts is equal to the current(I) in amps (or amperes, if you prefer) times the voltage (E) involts. The simplest example of a watt would be the amount of power thatyou would have if you had one volt at one amp of current. Or, toput it another way, 1 volt X 1 Amp=1 Watt. To go further, 12 voltsat 1 amp equals 12 watts. This is for direct current measurement. For AC voltage, it varies in that you would multiply the volts by.707 (AC RMS voltage), then multiply by the amps to get your wattstotal.

# How do get watts?

Watts = Amps x Volts

James Watt was a Scottish inventor who is famous for his improvements on the design of early steam engines. He became a major contributor to the Industrial Revolution.

# Is 1500 watts better then 800 watts?

It really depends on what you are needing. If this is for an air conditioner or ceramic heater, you may not need one that big. If this is for an outdoor light to light an enti…re yard, you may want the bigger wattage. â–

# Can you grow weed with a 100 watt light bulb?

# What is 100 watts?

Watts is a unit of power that is equal to volts x amps x Power Factor. Answer The watt is the SI unit for power. Power is defined as 'the rate of d…oing work'. Since work is measured in joules, the watt is equivalent to (a special name given to) a joule per second. The watt is sometimes described as measuring 'electrical' power. In fact, there is no such thing as 'electrical' or 'mechanical' (etc.) power, as power is simply a rate.

# What is is a watt?

# Why is a 100 watt bulb brighter than a 25 watt bulb?

Because it takes more current and power and produces more light power. Running a 100 w lamp costs 4 times more than a 25 w lamp.
