What shape is a sine wave? A sine wave is a geometric waveform that oscillates (moves up, down or side-to-side) periodically, and is defined by the function y = sin x. In other words, it is an s-shaped, smooth wave that oscillates above and below zero. What are 3 types of progressive waves? 8.1) Compare […]

Does PWM change voltage?
Does PWM change voltage? 3 Answers. PWM does not lower the (peak) voltage. PWM reduces the average current (and in consequence the average power). To reduce voltage you would have to add an inductor, catch diode and capacitors to make a buck converter which does lower the voltage. How do I control my 12v DC […]

Why is an alternator better than a dynamo?
Why is an alternator better than a dynamo? An alternator is a device that generates AC power from the rotation of an axle (mechanical energy). They are a bit similar to dynamos, but differ in the fact that they make AC power, whereas dynamo’s generate DC power. In addition, they also tend to be more […]
What are the factors affecting ship stability?
What are the factors affecting ship stability? Stability is determined by the force of buoyancy provided by the underwater parts of a vessel, coupled with the combined weight of its hull, equipment, fuel, stores and load. These forces can also be adversely affected by the prevailing weather conditions and sea-state. What are the various factors […]
