This degree is designed for students who plan to transfer to a four-year engineering program. In electrical engineering, the power factor of an AC electrical power system is defined as the ratio of the real power flowing to the load to the apparent power in the circuit, and is a dimensionless number in the closed interval of −1 to 1. This paper. To be adequately prepared for the first-year engineering program at Princeton, students should take high-school mathematics through calculus (if possible), as well as high-school physics and chemistry. Apparent power is the product of the current and voltage of the circuit. I am putting these here to remind me to post, I am an older student but dropped out in 7th grade but having a background in fixing things helps me connect the math theory to the real world. I don't have examples but so far in my EE program it's been a good bit of differential equations which is pretty important to know. Real power is the capacity of the circuit for performing work in a particular time. Calculating power in a waveform ( V and I ) -- from the simple AC 60Hz case, to a more complex PWM signal, or the losses in a switch... To append to an example like this, I would explain to students that calculating power is very important because it tells how much a certain component heats up, and if the power consumed by the component is greater than the power rating, then you run the risk of this component failing (visibly smoking or maybe even catching on fire in the right circumstance). is now available.
