Q

The device that most commonly utilizes the principle of electromagnetic induction by mutual inductance is what?

🔍 Key Concepts

• Electromagnetic induction – voltage induced by changing magnetic fields • Mutual inductance – when a changing current in one coil induces voltage in another nearby coil • Basic roles of a diode, transformer, transistor, and rheostat in DC/AC circuits

💭 Think About

• Which of these devices is specifically designed with two windings or sections that interact through a changing magnetic field? • Which components mainly control current flow in one single path, rather than transferring energy between two separate windings? • Think about AC power systems on ships: which device is used to step voltage up or down using coils and magnetic fields?

✅ Before You Answer

• Identify which option is built around two or more coils that are magnetically linked • Eliminate components that primarily act as semiconductors (solid‑state) rather than magnetic devices • Confirm which option is standard equipment in AC power distribution because of mutual inductance
