🔍 Key Concepts

• How transformers work (magnetic field in the core caused by changing current) • Difference between AC (alternating current) and DC (direct current) in terms of changing vs steady current • What happens in a transformer if current is not changing versus periodically changing or interrupted

💭 Think About

• Ask yourself: Does a transformer need a changing magnetic field to induce voltage in the secondary winding, or can a steady, unchanging current do the same job? • Think about what happens if DC is applied to a transformer and left on: what happens to the core, the windings, and the induced voltage after the first instant? • How would interrupting or pulsing a DC source change the situation compared to pure, steady DC?

✅ Before You Answer

• Verify that a steady DC produces a magnetic field that does not change over time after the initial switch-on moment. • Confirm that Faraday’s law of induction requires a changing magnetic flux to induce voltage in the secondary winding. • Check whether pulsed or interrupted DC effectively behaves like an AC signal from the transformer’s point of view.
