What will be the expected secondary voltage when 20 volts are applied to a transformer with a primary of 200 turns and a secondary of 500 turns?

• A. 10 volts
• B. 25 volts
• C. 50 volts
• D. 100 volts

Answer: (C)

To determine the expected secondary voltage in a transformer, you can use the transformer turns ratio formula, which relates the voltages and the number of turns in the primary and secondary windings. The formula is as follows: \[ \frac{V_s}{V_p} = \frac{N_s}{N_p} \] Where: - \(V_s\) is the secondary voltage, - \(V_p\) is the primary voltage, - \(N_s\) is the number of turns in the secondary winding, - \(N_p\) is the number of turns in the primary winding. In this case, the primary voltage (\(V_p\)) is 20 volts, the primary turns (\(N_p\)) are 200, and the secondary turns (\(N_s\)) are 500. Plugging these values into the formula gives: \[ \frac{V_s}{20V} = \frac{500}{200} \] Calculating the right side, we find: \[ \frac{500}{200} = 2.5 \] This means: \[ \frac{V_s}{20V} = 2.5 \] To find \(V_s

To determine the expected secondary voltage in a transformer, you can use the transformer turns ratio formula, which relates the voltages and the number of turns in the primary and secondary windings. The formula is as follows:

[

\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 turns in the secondary winding,

• (N_p) is the number of turns in the primary winding.

In this case, the primary voltage ((V_p)) is 20 volts, the primary turns ((N_p)) are 200, and the secondary turns ((N_s)) are 500. Plugging these values into the formula gives:

[

\frac{V_s}{20V} = \frac{500}{200}

]

Calculating the right side, we find:

[

\frac{500}{200} = 2.5

]

This means:

[

\frac{V_s}{20V} = 2.5

]
