A 3 Ω resistor carries 4 A. Find voltage and power.
Structure a solution for “Potential and voltage”: givens, SI units, law, substitution, and interpretation.
Identify three uncertainty sources in measuring “Circuits” and improve each one.
Plan a suitable graph for “Capacitors introduction” data and explain how to obtain a gradient or relationship.
Check whether a result for “Magnetic field introduction” is sensible using units, order of magnitude, and a limiting case.
Connect “Electric field” to energy conservation or a force/field model and justify the choice.
Write a multi-step exam response about “Potential and voltage” with calculation and evaluation.
Compare two methods for investigating “Circuits” and select the more reliable using criteria.
