Gas-powered vs. Electric Cars: Which Is Faster?
WebIf you're comparing an electric car and a gas car with the same horsepower rating, the electric car is able to use a lot more of its horsepower, too. That's because EVs have … WebHorsepower (hp) = Voltage x Amperage x % EFF x power factor x 1.73/746. = 472V x 20A x 0.90 x 0.85 x 1.73/746 = 17 Hp. The quickest method to closely estimate motor horsepower is to use a digital clamp meter to measure current and voltage to the motor, and then perform a simple calculation. tap the windows key or start button
Force, Speed and Horsepower - UGA
WebHorsepower in automotive terms is the application of a force at a certain speed. If you double the speed but halve the force, you are producing the same horsepower. If you double the force but halve the speed – again the horsepower is the same.
