It can also be expressed as amp = volt/ohms ![]() I (A) = V (V) / R (Ω), which means that the current in amps is calculated by dividing the voltage in volts by the resistance in ohms. Click on the ‘Calculate' button to give you the results in amps. If you select this option as your type of calculation, you need to enter the correct values of the volts and ohms in their required fields. If an electrical circuit has a power consumption of 56 watts with 20 V as the voltage supply, what is the current flow? I (A) = P (W) / V (V), which means that the current in amps is calculated by dividing the power in watts by the electric voltage in volts. ![]() The results in amps will be displayed on the bottom platform of the calculator, and the accuracy always depends on the values entered in the text fields. Click on the ‘Calculate' button to initiate the conversion. If you select this option as your calculation, you need to enter the correct values of the volts and the watts in their respective fields. The reason why you need the watts or ohms values to find the result in amps is that of the difference in the quantities of the units. It can either be the volts to amps with watts or volt to amps with ohms. Before you enter the values, you need to select the type of calculation. It is used to convert the electrical voltage in volts (V) to the current in amps (A). What is a Blog and Why Do You Need One to Make Money Online from Your blog.You can also convert electric current using one of our ampere converters below. You can also use a calculator, such as one of the converters below, for the conversion.Ĭommon ampere values and equivalent imperial and metric electric current measurements Then, multiply the electric current measurement by the conversion factor to find the equivalent value in the desired unit of measurement. You can find the conversion factors for amperes in the conversion table below. To convert amperes to another unit of electric current, you need to multiply the value by a conversion factor.Ī conversion factor is a numerical value used to change the units of a measurement without changing the value. In 2019, the ampere was redefined as the electric current corresponding to the flow of 1/(1.602 176 634 × 10 -19) elementary charges per second. Will produce a force equal to 0.0000002 newtons per meter of length. The ampere was previously defined as a constant current that when passed through two straight and parallel conductors that are spaced one meter apart, The ampere, commonly referred to as an "amp," is the electrical current constant equal to the flow of one coulomb per second. The ampere was originally defined as one-tenth of an abampere, but has been redefined several times since. The ampere is named for French physicist André-Marie Ampère to credit his work in electromagnetism and electrodynamics. The current in amperes is equal to the potential difference in volts divided by the resistance in ohms. Using Ohm's Law, it's possible to express the current in amperes as an expression using resistance and voltage. Ohm's Law states the current between two points on a conductor is proportional to the voltage and inversely proportional to the resistance. Amperes can be abbreviated as A for example, 1 ampere can be written as 1 A. An ampere is sometimes also referred to as an amp. ![]() The ampere is the SI base unit for electric current in the metric system. He holds several degrees and certifications.Īn ampere is a unit used to measure electric current.
