The vertical stabilizer is to provide additional anti torque force to the fuselage once the aircraft has forward motion and airflow across the lifting surface. The design makes use of forward motion and the resulting airflow to create an anti torq...
Yes, no matter what the model, a stabilizer is required. There is no stabilizer inside the refrigerator. Refrigerator companies claim that it can work at both, low and high voltage. But operating the refrigerator at a low voltage affects its cooling efficiency and its life.Also, there is no low voltage cut-off & high voltage cut-off in the refrigerator.This is the reason major refrigerator companies insist on using a good quality voltage stabilizer, in their warranty card. simple way to select the right stabilize. 1  Check the Voltage & current rating of the device. 2  In India typically the voltage will be 220V. 3  Multiply 220 x Current of all devices and then add the individual device's VAs. 4  You should also consider the surge current which flows when you switch on the device.
