A transformer works **only with AC (Alternating Current)** — **not with DC (Direct Current)**.
Here’s a simple way to understand it:
- A transformer needs a **changing magnetic field** to work.
- **AC** keeps changing its direction and size (positive to negative and back), so it **creates a changing magnetic field**.
- **DC** flows in only one direction and stays constant, so it **does not create a changing magnetic field** — and without a changing magnetic field, the transformer **cannot work**.
**In short:**
✅ Works with **AC**
❌ Does **not work with DC**

Would you also like me to explain **why DC can even damage a transformer** if applied? It’s an important point for students to know!
