What to Focus On

  • A cell gives energy to charges in a circuit.
  • Electrical power is P = V_AB × I.
  • Heat produced in a resistor is H = V_AB × I × t.

  • Current through a resistor produces heat.
  • Nichrome is used in heaters and cookers.
  • Tungsten is used in electric bulbs.

  • Home supply uses live, neutral, and earth wires.
  • The live and neutral wires have 220 V potential difference.
  • A fuse wire melts on high current and breaks the circuit.

Common Mistakes to Avoid

Electric power and electrical energy are the same thing.

Joule's law of heating is H = V_AB × I × t only.

Ohm's law is just a general statement about heat or power.
