What to Focus On

  • Electrical energy is transferred when current flows through a conductor.
  • Electrical appliances convert electrical energy into other forms.
  • Electrical energy shows chemical, heating, and magnetic effects.

  • Electrical work: W=QV, W=Vit, W=i^{2}Rt, W=V^{2}t/R.
  • Electrical power: P=W/t and also P=Vi, P=V^{2}/R, P=i^{2}R.
  • 1 watt means 1 ampere flowing at 1 volt.

  • Power rating gives energy used per second at rated voltage.
  • Resistance can be found using R=V^{2}/P.
  • Safe current can be found using i=P/V.

Common Mistakes to Avoid

Power and energy are the same thing.

The fuse should be connected in the neutral wire because current returns through neutral.

A switch can be connected in either wire without any safety issue.

Memory Tips
