🔍 Key Concepts

• Electromagnetic relay basic parts (coil and contacts) • Difference between protective devices (like overloads or fuses) and control devices • What happens when current flows through a coil in a relay

💭 Think About

• Ask yourself: when the coil of a relay is energized, what physical action happens to the contacts? • Which choice describes a device used to control another circuit from a distance rather than just protect from too much current? • Does a relay always act only in an overload, or can it operate whenever the coil is energized?

✅ Before You Answer

• Identify which options describe overload protection versus remote control of contacts • Check which choice specifically mentions a coil operating contacts • Eliminate any option that only talks about overcurrent/overload without mentioning a coil and contacts.
