3. AC in reality much more deadly compared to DC (i know u will say DC is more deadly but u will come to know about it in class 12)

4. it can be used to induce emf in coils

DC

1. magnitude of current remains same

2. direction of current dosent changes ie remains same

3. DC is less deadly compared to AC

4. it can't be used to induce emf in coils

hope this helps
