. 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)
