分步代入计算过程

01Canonical Law: V_s = V_p × (N_s / N_p)

02Given Inputs (Base Units): V_p = 240 V, N_p = 500, N_s = 50

03Solve for V_s (Secondary Output Voltage): V_s = 24 V

Faraday's Law of Electromagnetic Induction dictates that in an ideal magnetic-core transformer, the ratio of secondary to primary RMS voltage equals the ratio of secondary to primary winding turns: V_s = V_p × (N_s / N_p).
