Alternating voltage in any alternating current circuit is V = 50 sin (157 t + ϕ) V, then find out the: (i) root mean square value of alternating voltage. (ii) frequency of the alternating voltage.
Given V = 50sin (157t + ϕ) Compare V = Vm (sin ωt + ϕ) ∴ Vm = 50 volt and to = 157 rad/sec (i) Root mean square value of voltage
