## How many watts are in a 12 volt battery?

A 12 volt 1ah (amp hour) battery is rated to put out

**12 watts**for 1 hour before it is fully discharged. Or it could do 24 watts for a half hour. A 12 volt 2ah battery can put out 24 watts for 1 hour or 48 watts for half an hour.## How do you convert volts to Watts?

To obtain Volts you need both Watts and Amps:

The formula is **(W)/(A) =(V)**. For example, if you have a power of 10W with a current of 2A the voltage is 10W / 2A = 5V. This comes from the equation V = P / I. Where P is the power in Watts, I is the current in Amps and V is the voltage in Volts.

## How many watts does A TV use?

Electricity Use By TV Type

Size | LCD | LED |
---|---|---|

30 inches | 60 watts | 50 watts |

42 inches | 120 watts |
80 watts |

50 inches | 150 watts | 100 watts |

## How many watts does A refrigerator use?

The average home refrigerator uses

**350-780 watts**. Refrigerator power usage depends on different factors, such as what kind of fridge you own, its size and age, the kitchen’s ambient temperature, the type of refrigerator, and where you place it.## How much is 240 volts in Watts?

How many Volts are: | Equivalence in Watts |
---|---|

120 Volts | Equivalent to 1662.77 Watts |

127 Volts | 1759.76 Watts |

220 Volts | 3048.41 Watts |

240 Volts | 3325.54 Watts |

## What is the difference between A volt and A watt?

Volt is the measure of potential difference within two terminal of a conducting wire. Watt is the rate at which electrical work is performed when a

**current of one ampere**flows across the potential difference of one volt.## Is Hertz the same as Watts?

They are not comparable. Hertz is a unit of frequency.

**One Hertz (Hz) is equal to one cycle (or oscillation) per second**. Watts (W) are a unit of real electrical power, which is the product of voltage times current, times the cosine of the phase angle between them (you can ignore this last part).## Which is bigger watt or volt?

The symbolic representation of the

…

Comparison Chart.

**volt**is V. The measurement taken in volts is easier as compared to watts because watts is the product of the two quantity i.e., voltage and current. The watt is represented by W.…

## What is the value of 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.## How do I calculate wattage?

The formula for calculating wattage is:

**W (joules per second) = V (joules per coulomb) x A (coulombs per second)**where W is watts, V is volts, and A is amperes of current. In practical terms, wattage is the power produced or used per second. For example, a 60-watt light bulb uses 60 joules per second.## How many watts are in a ampere?

120 watts

How many watts make an amp? At 120V,

**120 watts**make 1 amp. That means that 1 amp = 120 watts.## What is difference between AC and DC?

Alternating Current (AC) is a type of electrical current, in which the direction of the flow of electrons switches back and forth at regular intervals or cycles. …

**Direct current**(DC) is electrical current which flows consistently in one direction.## How much is 1000 watts in volts?

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

**100 volts**.## How many batteries do I need for a 2000 watt amp?

When it comes to batteries, a 2000 watt inverter needs 24 volts to generate power. You would be able to use

**100Ah x 24Ah if**you used 2 batteries of 12 volts 200Ah.## How amps does a refrigerator pull?

Amperage for most household refrigerators, is anywhere from

**3 to 5 if the voltage is 120**. A 15 to 20 amp dedicated circuit is required because the in-rush amperage is much higher. The average amperage is lower because the compressor isn’t running all the time, this is often measured in kilowatt hours KWH.## How many amps does a fridge use?

Generally, a fridge uses

**about 6 or 7 amps**, but triple that for the start-up surge, Accordingly a dyed-in-the-wool authority pipe with 15 to 20 amps is compulsory for a fridge. It must be the sole piece of equipment plugged into that outlet.## Do I need a bigger alternator for two batteries?

**You can run two batteries on the same alternator**. Alternators protect against excessive current drain and aren’t affected by multiple batteries.

## How many volts does a subwoofer need?

As you know the subwoofer installed in your car works on battery that delivers

**12 volts**to all your audio setup.## Can subwoofers damage your alternator?

**Subwoofers on their own cannot damage your alternator**. However, subwoofers combined with their amplifier and the corresponding amplifier can damage your alternator if it draws too much power from your battery. And this can cause the alternator to overheat and potentially damage.

## How big of an alternator do I need for 3000 watts?

250A

3000 watt / 12V is equal to

**250A**. A 250A alternator is needed to keep up with it. Since your engine would have to work just as hard as any portable 3KW generator to keep up with the amplifier, you would need a large fuel tank.
