MHT CET 2023 Physics question
The a.c. source of e.m.f. with instantaneous value 'e' is given by e = 200 sin (50t) volt. The r.m.s. value of current in a circuit of resistance 50 is
Answer: (B)
Solution
Compare with : the peak e.m.f. is ( is not needed for a purely resistive circuit). Peak current: . R.m.s.
