What is wattage

A watt (W) is a unit of measurement of power. Watts therefore refer to the power of your device. Examples: an incandescent lamp has a power of 60 W. your microwave oven has a maximum power of 900 W.

What is a watt in simple terms?

Definition. The watt is a method of measuring the rate of energy transfer of an appliance. A one watt lightbulb, for example, will change one joule of electrical energy into light energy (and some heat/sound) every second, thus "consuming" it. It is a measure of an appliance's power (appetite for joules).

How much is a 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 is a wattage used for?

Watts measure power--kilowatt-hours measure energy Energy is defined as the capacity to do work, such as creating heat, light, or motion. If you run a 60-watt lightbulb for one hour, you've used 60 watt-hours, or 0.06 kilowatt-hours, since a kWh is 1,000 watt-hours.

Is higher Watts better?

Higher wattage = more power. When considering the capacity of your power supply, there's one rule of thumb that's important to remember. It's better to have more power than you need because you shouldn't run your power supply at 100% capacity.

How much does 700 watts cost?

It's 700 Wh (0.7 kWh) per week, or 36.525 kWh per year. With the same $0.13 per kWh price of electricity, your hoover costs you $4.75 per year.

How many volts are in watts?

If you have a 1 amp circuit, 1 volt is equal to 1 watt. If you have a 100 amp circuit, 1 volt is equal to 100 watts.

How many watts is 220 volts?

P (W) = 1 A * 220 V = 220 W At 220V, 1 amp is equal to 220 watts.

What does 60W mean?

Energy by the Hour Its 60W rating means that for each second that it's on it uses 60 joules of energy. Over the course of 60 minutes, or 3,600 seconds, this means it would use 216,600 joules of energy.

How many watts does a fridge use?

Domestic fridge power consumption is typically between 100 and 250 watts. Over a full day, a fridge records between 1 to 2 kilowatt-hours (kWh) of total energy usage, or about $150 per year per fridge.

What uses a lot of electricity?

How many Volts is 1000 watts?

Divide 1000 watts by 10 amperes and the resultant voltage would equal 100 volts.

Is more watts better for lights?

Energy efficient light bulbs – more lumens, less Watts The most efficient energy saving lights produce the most light (lumens) using the least electricity (Watts). Energy efficiency in lighting products is given in lumens per Watt (lm/W) – the higher the number, the more energy efficient.

Is 400 watts a lot of power?

On the other hand, 400 watts will be fine if you want to power a small laptop (rated 50 watts), a wall fan (45 – 60 watts), and a 32'' CRT TV(120 watt). Your calculator should read 230 watts (50+60+120).

What happens if you use too many watts?

Using a light bulb with too high of wattage can lead to overheating of the light bulb. This heat can melt the light socket as well as the insulation of the wires. Once that happens, you put yourself at risk of arc faults, and this is something that could even lead to property fires.
