To obtain amperage from a formula you need at least two components. Formula for amperage are I = W/E, I = E/R and I = sq root of W/R.

What is the ampere rating for a 12 volt 12 watt battery?

Batteries are generally not listed as having watts. And there are a couple of different ampere ratings. But if you're running something needing 12W of a 12V battery it's pulling 1A out of the battery at the moment.


Can you replace 50 ampere car battery with 60ampere?

Yes as long as it is 12 volts.


What is the resistance of an electric frying pan that draws 12 amperes of current when connected to a 120 volt circuit?

Given R=? I=12 ampere V=120 Volts equation I=V divided R Solution; R=12 ampere 120 Volts answer (10)


Is there 1200 watts in 12 volts?

If the 12V source can deliver 100 Ampere, then yes. If it can't, then no. (remember watts / volts = amps)


How much watts in one ampere?

Since the equation for watts is: Volts * Amps = Watts that would mean 12 Volts * 1 Amp = 12 Watts


What is the maximum wattage for 5 amp fuse?

The 5 amp fuse has many wattages that it can protect. It depends on the voltage of the circuit that the fuse is protecting. Use the following formula, Watts = Volts x Amps. For example 120 volts x 5 amps = 600 watts, 240 volts x 5 amps = 1200 watts, 480 volts x 5 amps = 2400 watts and 600 volts x 5 amps = 3000 watts.


What does 1.5 watts equal to amp using 12 volts?

volts times amps equal watts. So 12 volts times ? amp equals 1.5 watts. The current is 1.5/12 amps, which is 1/8 amp.


Convert 216watts to Ampere Hour?

You can not convert Watts (Power) to Ampere-Hours (Amount of charge)!!! Exept if you know the voltage and the amount of time you use the power. For example: If you use P=216 W from a battery of V=12 Volts for t=1 hour, that would be: Current I=P/V=216/12=18 Amperes In time of 1 hour, you will take Q=I*t=18 Ampere-Hours from the 12 Volts battery.


How much are 12 ampere in volt?

12 va These are two different entities. Its like asking how much water will flow with pressure. With the following formula W = Amps x Volts you can see the relationship they have with each other, the end product resulting in Watts.


How long will a battery 12 ampere-hour rating supply 144 watt load?

An ampere-hour rating is a relatavistic indication of how long a battery can supply a specific current.It is not possible to determine the run time when you only gave watts, but watts are volts times amps, and you did not supply the volts.


How many amps DC is 12 volts 1.5 amps at 5 volts?

To calculate the amperage at 12 volts based on 1.5 amps at 5 volts, you can use the formula P=IV (Power = Current x Voltage). First, find the power at 5 volts (P=1.5A * 5V = 7.5 watts). Then, using P=IV at 12 volts, solve for current (7.5W = I * 12V => I = 0.625A). So, at 12 volts, 1.5 amps at 5 volts translates to approximately 0.625 amps.


What is the watts if a 12 volt battery produces 2.7 amps?

The power output of a 12-volt battery producing 2.7 amps can be calculated using the formula: Power (watts) = Voltage (volts) x Current (amps). So, in this case, the power output would be 12 volts x 2.7 amps = 32.4 watts.
