. If instantaneous current in a circuit is given by I = (2 + 3 sin ωt) A, then the effective value of resulting current in the circuit is (1)(17/2)1/2 ampere (2) (2/17)1/2ampere (3)(3/(2)1/2)1/2ampere (4) 3(2)1/2ampere Share with your friends Share 80 Vara answered this Instantaneous current:I=Idc+Iac =a+bsinωtCompare with the given equation of I=2+3 sinωtThen,a=2andb=3Effective current=a2+b22 =22+322 =172 amperesAns:Option-1 218 View Full Answer
