. Most all circuit breakers have the amperage stamped onto the switch handle of the circuit breaker. If you have light bulb that is a 60Watt bulb that runs off of 120Volts it draws 5 Amps but a 250Watt bulb that works off of 120Volts draws 208 Amps each. Steps to Calculate Your Breaker Panels Total Amps. On the following page click First Time User.

The current I in amps A is equal to the power P in watts W divided by the voltage V in volts V. If you want to know how many amps your batteries have youll need to do some arithmetic. 4160 Watts 208 Volts 20 Amps. If you want to find Amps you need to know the voltage a piece of equipment runs off of and the Watts.

Enter the amps watts and select the calculation type watts or ohms and the amps to volts converter will convert it to volts. IVR or current equals voltage divided by resistance. Hence for calculating primary current I P-A in Amps will be. The phase current I in amps A is equal to the real power P in watts W divided by the power factor PF times the RMS voltage V in volts V.

The current I in amps A is equal to the voltage V in volts V divided by the resistance R in ohms Ω. AC single phase watts to amps calculation formula. The current I in amps A is equal to the square root of the power P in watts W divided by the resistance R in ohms Ω. I P-A S kVA 1000 1732 V P-V V P-V is the primary voltage in Volts.

Once you pick a value look for the corresponding electrical current amperes DC Calculation. If you know the resistance of the batteries you can use Ohms Law to calculate the amps from the voltage. An ampere hour or amp hour is a unit of electric charge or current flow over time. After the steps above the final formula for converting horsepower to amps is.

2400 Watts 20 Amps 120 Volts. Calculate the electric charge in amp hours. I A P W PF V V So amps are equal to watts divided by power factor times volts. Our goal here is to get the amps in your breaker panel before adding more circuit branches.

The simplest way to convert from Amps to resistance is by the formula of Ohms law dividing the voltage between the current. Amps to Volts calculator to convert amps to volts. Watts Watts η.

Given data is 20 hp and we need to find the amps rating. 3600 Watts 240 Volts 15 Amps. Hi Joe From what you have described you can see the capacity of your electrical panel by looking at the main circuit breaker which is typically the largest breaker in the panel located at either the top or to the left side depending on your panel. Find a watts to amps conversion table.

I A P W PF x V V 186 W 04 X 110 V 2943 amps A Calculating the AC three phase watts to amps Line to line Voltage I A P W 3 x PF x V L-L V which means that the phase current in amps is computed by dividing the real power in watts by the multiplication of square root of three time the power factor. I S-A S kVA 1000 1732 V S-V. The table above works too. To calculate how many volts in an amp divide watts by amp.

Amps Watts Volts. To find the amp capacity of your breakers inside the panel box itself you can use the Power formula IPV. After the power has been converted to watts use the Watts Law formula to find current in amps. Click Here to Register Select your user type.

To find this divide the horsepower by the efficiency η in decimal form. Formula for finding Amperes when Horsepower is known in direct current dc and alternative current ac. Amps watts PF volts or. By dividing watts over volts you can find the Ampers or resistance of your equipment ex.

Suppose a battery provides 200 Amps for 3 hours. DLA DOD employee DOD Contractor or US Military personnel select Federal Agency User Contractor. Amps Watts Volts Examples. For example if you have an electronic processor with a voltage of 5V DC and an amperage of 02 Amp you must divide 5 by 02 as follows 5.

Hence the formula for secondary current I S-A in amps will be. For example a 120-watt device requiring 1200 volts requires 10 amps. Formula to calculate amps hours. Table of Contents hide What You Will Need.

Divide the number of watts required by the volts to determine the needed amperage. Navigate to the AMPS Website and select the Click HERE for Access to AMPS Link. P 3 v i cos i p 3 v cos i 14921000 1732 415 08 i 2594 a i 26 a. The ampere often shortened to amp is the base unit of electric current in the International System of Units.

Heres how you can calculate amps using watts and direct current DC voltage.
