When an electric current is passed through a metallic wire, the wire gets heated up. This is known as heating effect of current.

Uses of heating effect of electric current:

1. Electric room heater or an electric heater
2. Electric Fuse
 
 
When electric current passes through a wire, it behaves like a magnet is called the magnetic effect of electric current.
  • Uses of magnetic effect of electric current:
When a compass is brought near a current-carrying conductor, the needle of the compass gets deflected because of the flow of electricity. This shows that electric current produces a magnetic effect.

Electric current is the flow of electrons. So, it should flow from the negative to the positive terminal. But my teachers say that the conventional direction of the current flow is high (positive terminal) to low (negative terminal) potential. Which statement is true? If both are true, then why? And please explain to me the difference between Direct and Alternating current. Please help, my exams are coming.
