Answer

Explanation:

Step1: Use the transformer voltage - coil relationship formula

The formula for a transformer is (\frac{V_s}{V_p}=\frac{N_s}{N_p}), where (V_s) is the secondary voltage, (V_p) is the primary voltage, (N_s) is the number of secondary coils, and (N_p) is the number of primary coils. We are given (V_s = 10000\space V), (V_p=25000\space V), and (N_p = 200).

Step2: Solve for (N_s)

From (\frac{V_s}{V_p}=\frac{N_s}{N_p}), we can cross - multiply to get (N_s=\frac{V_s\times N_p}{V_p}). Substitute the given values: (N_s=\frac{10000\times200}{25000}). First, calculate (10000\times200 = 2000000). Then, (\frac{2000000}{25000}=80).

Answer:

80 coils
