1 ampere how many volts

We take the distance into consideration to calculate the voltage loss. The other half of this calculation is the current. You need a larger wire to move more current. If you have a choice the higher voltage is best. These formulas are also useful in calculating AC alternating current wattage to determine the size of an inverter, which converts the DC electricity from a solar array to AC that can then be used to power lights and appliances in homes and businesses.

Appliances include a face plate which contains all of its electrical data. Lets suppose you have a microwave oven. The manufacturer will list an amp requirement on the electrical data of the face plate, which is usually attached to the back of the oven. Let's say that the rating on the face plate is 8. To calculate the watts, multiply 8.

This equals watts. Now, lets calculate how much power the microwave will use in one day. If you use the microwave for 2 hours a day, then multiply the hours per day by the watts to get watt-hours per day. So, you have watts multiplied by 2 hours, which equals watt-hours per day. You already know you have 20 amps. Just include the voltage; either V or V. Hope this helps. On a site I am a member of we have a lot of people putting in multiple amplifiers into boats.

Often these amps are 15 feet away from the battery so the questions always come up…. This is 12V DC. So if I install 3 amps rated at watts each, feet from a battery, what size cable should I run to them? Hello Julian, an interesting question. So, you would need wires that can handle up to about amperes of current.

I am trying to power a watt 2 channel audio amplifier 12 v rms per channel. How many amps would I need the converter to put out? You would need your converter to put out 65 amps minimum. I have 4 ea. Each of these units draws a bit less than 15 amps. For 15 amps, you can use gauge wires. Hope you find this useful. Hello Willy. Be aware that solar panels produce electricity at a lower voltage 12V or 24V.

To get 16, Watts at 24V, you would need I want to purchase a heat press that has a v plug. It uses watts. Would a 30amp breaker be enough? Hello Darica, watts at V is a little below 30 amps. Hello Chris, kW is a huge wattage. You can use the electric power equation to easily see how many amps would be sufficient.

Hi … trying to learn about all this because my kitchen actually my whole house is electrically challenged. My fridge is I would think this would be too much to run both at the same time, but they have never thrown the circuit.

Am I doing the math right? Hello Sandra, do both run on V? If they run on V, the amps are halved. Additionally, the fridge might draw Most fridges run on much a lower percentage and hence draw much fewer amps. I have an inverter AC watts, v. With the equation you provided, it consumes 7. Is this a feasible setup? Am I correct in saying I can run the AC even 24hrs? Hello Franz, two Ah batteries have a Ah capacity. By this we mean that this battery can be compared to a lead battery with the indicated capacity when used in combination with an electric motor.

Often a lithium battery with a much lower Ah can in practice deliver the same amount as a lead-acid battery with a much higher Ah.

In practice, for example, the Rebelcell 12V50 can be compared to a Ah semi-traction battery in terms of operating time for an electric motor. This also has everything to do with the usable battery capacity.

Nominal energy: this is the battery capacity measured in watt-hours see above for explanation. Maximum continuous discharge: this is the maximum number of amps the battery can continuously deliver. Suppose a battery has a maximum continuous discharge of 30A, then you cannot connect a device that draws more than 30A. The higher the capacity of the battery, the higher the maximum continuous discharge.

Peak discharge 10 milli-sec : this is the maximum number of amps the battery can deliver for 10 milli-seconds. This is always higher than the maximum continuous discharge. This is for example the case when you go from zero to full throttle in one go with an electric outboard engine. At that moment, the motor requires more amps than the rated maximum for a short time. Energy density: with this we measure the number of Watt-hours per kilo of battery. Energy density is much higher for lithium batteries than for lead-acid batteries.

A high energy density means that you can store more energy in the same space. And this results in a lighter and smaller battery. Bandwidth voltage: see explanation of the discharge and capacity of batteries. Charge temperature: this gives the minimum and maximum temperature at which a battery can be charged. Discharge temperature: this indicates the minimum and maximum temperature at which a battery can be discharged. Storage temperature: This indicates the minimum and maximum temperature at which a battery can be stored safely.

Maximum charge current: This gives the maximum current in A at which the battery can be charged. The higher this number, the faster the battery can be charged with the right battery charger. Integrated cell balancing: part of the Battery Management System. This is necessary for optimal use and performance of the battery.

Temperature protection: part of the Battery Management System. The battery is switched off when the temperature becomes too high or too low. This is a protection to prevent damage. Maximum discharge current protection: part of the Battery Management System. The battery is switched off when the power draw of your equipment is higher than is allowed.

Overvoltage protection: part of the Battery Management System. The battery is switched off when the voltage becomes too high and the battery is overcharged. Volt, Amps, Amp-hour, Watt and Watt-hour: terminology and guide.
