Know this first

Electricity questions depend on identifying charge, a conducting path and the condition that controls current or magnetic effect.

Charge is a property · current needs a conducting path

Charge is a property; current needs a conducting path. Decide first whether the question concerns charging, resistance, current or earthing.

Find the tested idea

Write down the quantities, directions or conditions given in the stem before selecting a formula or rule.

Work from the evidence

Use one governing relationship at a time. For a visual question, trace the path; for a numerical question, keep units and signs consistent.

Verify before choosing

Use the wording, diagram and units exactly as given. Select an option only after it satisfies every stated condition.

  • ✓Apply one governing rule.
  • ✓Check sign, unit or direction.
OlympIQ trap

Check the result against a simple limiting case, diagram direction or unit before choosing an option.
