When connected to boost the input voltage, how are primary and secondary voltages affected?

• A. They are equal
• B. They are subtractive
• C. They are additive
• D. They remain unchanged

Answer: (C)

When connected to boost the input voltage in a transformer, the primary and secondary voltages are additive. This means that the voltage on the secondary side increases relative to the voltage on the primary side. In a step-up transformer, the primary winding receives the input voltage, and the transformer adjusts it through electromagnetic induction to produce a higher output voltage in the secondary winding. The relationship between the voltages is defined by the turns ratio of the windings. For example, if a transformer has more turns of wire in the secondary winding than in the primary winding, it will effectively increase the voltage. This is governed by the formula Vp/Vs = Np/Ns, where V represents voltage and N represents the number of turns in the primary (p) and secondary (s) windings respectively. Here, when the secondary has more turns than the primary, it results in a higher output voltage. Thus, the correct answer articulates the fundamental operation of how transformers increase voltage by adding the values at the primary and secondary levels.
