  8. Heating Effect: Joule’s Law derivation \( H = I^2Rt \).
  9. Magnetic Fields: Field lines in Solenoids and Right-hand thumb rule.

Asterisk Classes: Scoring Strategy

  • Biology Diagrams: Labels should be on the right side only. Use a pencil for drawing but ink for labeling.
  • Chemistry Equations: Always write the physical state (s, l, g, aq) to get full marks for balancing.
  • Physics Numericals: Always state the “Given” values and the formula used before starting the calculation.
