Hebu tutatue hili: Step 1: Tafuta voltage ya kilele (peak voltage), V₀. Voltage ya AC ya 220 V ni RMS voltage (V_rms). Ili kupata voltage ya kilele (V₀), tunatumia formula: V_rms = V₀ / √(2); Hivyo, V₀ = V_rms × √(2); V₀ = 220 V × √(2); V₀ = 220 V × 1.414; V₀ = 311.08 V Step 2: Tumia formula ya wastani wa EMF (average EMF) kwa nusu mzunguko chanya. Kwa wimbi la sine, wastani wa EMF (V_avg) wakati wa nusu mzunguko chanya hutolewa na formula: V_avg = (2V₀) / π Step 3: Badilisha thamani ya V₀ na ukokotoe. V_avg = (2 × 311.08 V) / π; V_avg = 622.16 V / 3.14159; V_avg = 198.04 V Wastani wa EMF wakati wa nusu mzunguko chanya ni 198.04 V.
