give an expression for average value of ac voltage v=vmsinwt over time interval t=0 and t = π / w Share with your friends Share 4 Neha Gupta answered this Average value is given by :Vavg= 1T∫0TVmsinωtdtwhere T is the time peiord over average vlaue need to be calculated.T = πωVavg = ωπ∫0 πωVmsinωtdt=-* ωVmπcosωtω = Vmπ-1-1 = 2Vmπ 9 View Full Answer Sree Parvathi answered this when t = 0 .v = 0 since sin 0 =0when t= pi / w, v= vm sin w pi /w = vm sin pi = vm -9
