#2.4 amps to watts software
One Ampere is defined as the current that flows with electric charge of one Coulomb per second.Ĭurrently, we have around 1977 calculators, conversion tables and usefull online tools and software features for students, teaching and teachers, designers and simply for everyone. The Ampere unit is named after Andre-Marie Ampere, from France. One watt is also defined as the current flow of one ampere with voltage of one volt.Īmpere or amp (symbol: A) is the unit of electrical current. One watt is defined as the energy consumption rate of one joule per second. The watt unit is named after James Watt, the inventor of the steam engine. You can calculate (but not convert) the amps from watts and volts: Amps calculation with voltage of 12V DCįor DC power supply, amps are equal to watts divided by volts.Īmps = 800W / 12V = 66.667A Amps calculation with voltage of 120V ACįor AC power supply, amps are equal to watts divided by power factor times volts.įor resistive load without inductors or capacitors, the power factor is equal to 1:įor inductive load (like induction motor), the power factor can be approximately equal to 0.8:Īmps = 800W / (0.8 × 120V) = 8.333A Amps calculation with voltage of 230V ACĪmps = 800W / (0.8 × 230V) = 4.348A Watt definition
