The isolation transformer provides electrical isolation between windings.

The isolation transformer provides electrical isolation between windings.

• A. False
• B. True
• C. Depends On Turns
• D. Only At Low Voltage

Answer: (B)

Isolating transformers are designed specifically to provide galvanic isolation between the primary and secondary windings. This means there’s no direct electrical path for current to flow from input to output—the energy transfer happens through magnetic coupling in the core, while the windings are insulated from each other. That insulation gives a high dielectric withstand, helping protect against shock and reduce ground loop issues. In practice, there can be a tiny leakage current due to inter-winding capacitance or parasitics, but this does not defeat the primary purpose of providing isolation. The isolation is a feature built into the design and rated insulation, not something that depends on turns or voltage level.
