Uniform Circular Motion:-Circular motion is said to the uniform if the speed of the particle (along with the circular path) remains constant. Angular Displacement:- Scalar form:- ?S = r?θ Vector...
current or voltage we measure for AC are alaways rms(root mean square) value not the actual magnitude so 220 volt ac(rms)= 220*sqrt(2)=311 volt but 220 volt DC alaways gives the magnitude...
