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.
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.
Yes as long as it is 12 volts.
Given R=? I=12 ampere V=120 Volts equation I=V divided R Solution; R=12 ampere 120 Volts answer (10)
If the 12V source can deliver 100 Ampere, then yes. If it can't, then no. (remember watts / volts = amps)
Since the equation for watts is: Volts * Amps = Watts that would mean 12 Volts * 1 Amp = 12 Watts
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.
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.
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.
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.
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.
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.
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.
