How Much Current Does An Amp Draw

Many years ago, in a High Schoolhouse Physics class, nosotros were introduced to Ohm'south Law. Only put, Ohm's Police states "The resistor's current I in amps (A) is equal to the resistor'due south voltage V_R=V in volts (V) divided by the resistance R in ohms (O):" To nigh, it's as confusing today, as it was the first time we heard information technology. By breaking information technology down, slice by piece, yous tin can utilise this nifty tool to calculate the amp draw of almost all electronic equipment, including LED lights.

To accurately figure the amp depict of whatsoever equipment, yous volition need 2 pieces of information. First, yous need to know the voltage (V) going to the equipment. The voltage may exist listed equally 120V Air-conditioning, meaning 120 volts of alternating current (standard household electric current), or 12V DC (standard bombardment electric current or from an Ac/DC power transformer). The 2nd piece of data you need is the wattage output of the electronic equipment you will be using. You lot can ordinarily find this information listed on the product label, or in the owner's manual. And so you take the wattage, and divide it by the voltage (100 watts / 12 volts = eight.33 amps.) This will tell y'all roughly the amperage your equipment will depict. You lot tin can utilize this appointment to decide if your power source is capable of fairly powering your electronics.

So while it may seem to be a daunting task, even the nigh novice electronics heir-apparent tin apply Ohm's Law to decide which products will work together. As in all purchases, taking time to research a production's requirements and abilities will pay off in the long run. In one case over again, some other instance of using science to simplify life!
