Current and auto transformers
Auto-transformer working principle. The working principle goes like this, one winding forms primary and secondary parts. In this case the number of primary windings are less than secondary and we have stepped-up voltage. On the input, the current will flow through the portion of the winding connected by these terminals.
Electrical Energy Storage: an introduction
Introduction. Electrical energy storage systems (EESS) for electrical installations are becoming more prevalent. EESS provide storage of electrical energy so that it can be used later. The approach is not new: EESS in the form of battery-backed uninterruptible power supplies (UPS) have been used for many years.
Working Principle and Components of Drone
Working principle of Drone-Quadcopter Dynamics. Throttle/ Hover: The up and down movement of the drone is called throttle. If all four propellors run at normal speed, then the drone will move down. If all four propellors run at a higher speed, then the drone will move up. This is called the hovering of a drone.
