How Do You Calculate Amps Without Watts? In the unlikely event that you don’t know the wattage of an appliance, but you do know the voltage (almost always 120V) and the resistance (ohms), you won’t be able toconvert watts to amps, but you can calculate the amperage of the device....
electricians are concerned with four different values; voltage, current, resistance and power. All four values are linked by Ohm's Law, a set of equations that shows the relationships between the main electrical units. Power and current, measured in watts and amps, respectively, are linked ...
Use Ohm’s law to calculate amps using resistance. Many appliances have a listed resistance. The wire connecting the circuit also has a variable resistance. In the same sense, you can fit less water through a garden hose than a fire hose. You don’t need to include this resistance unless ...
But there's a big "however". While it's fairly easy to determine the product of amperes and time that will be required for a given amount of plating, very complex phenomena determine the current you must apply to get satisfactory plating, and you're not going to be able to calculate th...
In theory, you can calculate the run-time for any of your battery's accessories by dividing the amp-hour rating of the battery by the amp draw of the accessory. You might have to convert from watts first. For instance, if you want to know how long you can bang a 1,000-watt stereo...
them and explain your correction. in the second circuit i would like to know how to calculate the total amps required by all of the leds in the circuit. one led requires 30ma, so i multiplied 30ma by 3 which is 90ma. is this the correct why to know the amps required by ...
Electric power, is the rate of doing work, measured in watts, and represented by the letter P. The term wattage is used to mean "electric power in watts." The electric power in watts produced by an electric current I consisting of a charge of Q coulombs every t seconds passing through...

Calculate the total current of your load: Using the formula: Current = Power (in watts) / Voltage, you can determine how much current your solar system must generate to run the connected electrical load. Assuming the power to be 1000 watts and voltage as 24 volts, current = 41.66 amps. ...
