If i=10+10sin314t then find the rms and average value of current with explain?
Answer Posted / vishal kumar bharti
Average value:
Since I=10+10sin 314t
We know that 10 =constant function and 10sin314t is symmetrical function
Therefore AVERAGE CURRENT=CONSTANT FUNCTION
SO, I =10 ampere
RMS CURRENT:-
RMS CURRENT=√ (DC)^2+(I/√2)^2
=√10^2+(10/2)^2
=√100+50
=√150
=12.2 ampere
