Unless you have an electric car that can do vehicle to load. That means that you can plug in regular household devices like your fridge.

LazaroFilm@lemmy.world 3 months agoWatt and volt are two different measures for electricity. Also your fridge will not work when hooked up to a car battery for many other technical reasons, including differ t voltages, and current types (AC/CD, not the band)

That vehicle isn’t using a traditional 12v car battery for that. Also the point t is you can’t connect a car battery to a fridge and expect it to work.

Yes. That not the “use a12v battery” assignment. It would be use an inverter…

So. The answer is yes you can. If the car is an EV with V2L. Which I am guessing is what that uncle was talking about in the post.
LazaroFilm@lemmy.world 3 months ago
V2L doesn’t relies on traditional 12v battery…

Not with that attitude!

Sure you can use the 12v battery and convert that power but you can’t just connect a 12v battery and expect it to work.

You stated that you cant connect a car battery to a fridge. You said nothing in your comment about 12v. I can connect my var battery to my fridge no problem.
LazaroFilm@lemmy.world 3 months ago
You can but it won’t keep your fridge cold. (Unless you use an inverter and you would need to check the amps needed by the fridge when the pump is on and see if your battery and inverter can provide that.

That’s wrong. Watt is a measure of power and volt measures…… voltage.
Charge (electricity) is measured in Coloumbs (sp?)
You need a complete circuit for Watts as P=iv.
I is current, measured in amperes
Serinus@lemmy.world 3 months ago
With the river analogy, Voltage = pressure, Wattage = how much water is passing, Current (Amps) is how wide the river is.
Pressure * Width of river = Amount of water passing
Not sure that helps with passing it through the terms and then to variables.

Water analogy works better with plumbing. A river, not so much. But people aren’t that much better at understanding plumbing, unfortunately…

Volts measure voltage?

Electrical potential, IIRC

Another way to think of it is this: Volts are like water pressure (potential energy) Amperage is like the flow rate of water Ohms (resistance) is like how hard it is to push water from high pressure to low pressure Watts are like the volume of water (a unit of energy)
A big hose has low resistance, water can move freely A coffee straw has large resistance, it’s hard to pull and push water thru it
A river has very low water pressure, and the speed of the water can vary, so volume of water moving can be huge so the flow rate of water can be huge as well. A pressure washer might have very high pressure, but use as much water as a kitchen faucet. Certain applications need high pressure, some need low pressure. A car battery is like a river, low pressure (typically 12volts) but move a lot of amps (cold cranking amps of up to 500-600 ish usually), and a wall outlet by comparison is like a pressure washer with 120v, 15A (in the US). A fridge won’t play nice on 12v, it needs 120v. It might need 400 watts which a car battery can do but it cares about how it can get that by requiring higher potential.
A watt, W=VA, can be thought of as asking how much water is there? 1 minute under a sink verse 1 minute in front a fire hose has two very very different amounts of water.
A watt hour, which most people are familiar with in the US for billing on their utilities, is like asking how many cups of water an hour. A light bulb needs a fraction of a kilowatt hour, a drier needs multiple kilowatt hours, but might only run for 30 minutes.
This idea gets a little tricky and falls apart at its edges but as a general idea should hold up for most peoples understanding of electrical stuff unless you work with it daily like an electrical engineer, electrician or something similar. For sanity sake I’m not going to try to apply this to AC verse DC, I don’t have a good analogy for that
