A ray hit a smooth regular surface at an angle of 20 from the normal. Calculate : 1. The angle btw the incident and reflection ray. 2. The angle of deviation.
As we use capacitior bank in 3ph ckt for improvement of PF, why not we use capacitor in single phase domestric use, at our house their are many inductive equipments,like fan,mixer,tube choke,air conditioner they also draw PF... by using capacitor can they improve PF. if yes--what are advantage and how to connect a capactor in single ph,and which type of capacitor if no- what are disadvantages.
If we want to change a contactor of faulty one what are the conditions want to fullfil
