An ac current is represented as i =5 2 +10 (650 t + 6 ) Amp The r.m.s value of the current is

Options

  1. A50 Amp
  2. B100 Amp
  3. C10 Amp
  4. D5 2 Amp

Correct answer

C. 10 Amp

Step-by-step solution

i=5 2 +10 (650 t+ 6 ) i ^2=50+100 ^2 (650 t + 6 ) +(2)(5 2 )(10) (650 t+ 6 ) i ^2 =50+ 100 2 +0 . i ^2 =100 i =10 Amp
