. An alternating curres given by nt is given by
by i = i1 cos ω t + i2 sin ω t. The rms current i
A: i1+i_2√(2)
B: |i1+i_2|√(2)
C: √(i12+i_222)
D: √(i12+i_22√(2))
Best Answer
Explanation:
i=i1Cosωt+i1Sinωt
Let I1=ISinθ………(1)
I2=ICosθ…………(2)
From equation (1)&(2) we get
√(i12+i_222)
Final Answer:
Hence, the correct option is (C ) I.e,√(i12+i_222)
