Ключевые идеи главы в понятной последовательности перед практикой.
Charge is a property, current is charge flow rate, and potential difference is energy per unit charge. Keep these definitions distinct.
Draw a closed circuit with correct symbols. Apply charge conservation at junctions and energy conservation around loops where required.
Field lines indicate direction and relative strength. In induction, changing magnetic flux is linked to induced potential difference.
For “Circuit symbols”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Series circuits”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Cells and bulbs”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Current introduction”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Conductors and insulators”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.

Следуйте методу шаг за шагом и проверяйте обоснование каждого шага.
A 5 Ω resistor is connected across 15 V. Find current and power.
I = 3 A, P = 45 W
Before calculating, explain the key idea from “Circuit symbols” and which conditions must be checked.
The answer should show not only which rule is used for “Circuit symbols”, but also why it is valid here.
Electricity, magnetism and space
Восемь заданий от базовых навыков до экзаменационного уровня. Сначала решите самостоятельно.
A 4 Ω resistor carries 6 A. Find voltage and power.
V=IR and P=VI.
V=24 V, P=144 W.
Structure a solution for “Series circuits”: givens, SI units, law, substitution, and interpretation.
State the law before substituting numbers.
A full solution states symbols/units, selects a valid law for “Series circuits”, shows substitution and calculation, and interprets the result.
Identify three uncertainty sources in measuring “Cells and bulbs” and improve each one.
Consider instrument resolution, reaction time, repeats, and controls.
A full response links each specific error source to a targeted improvement and identifies random or systematic impact.
Plan a suitable graph for “Current introduction” data and explain how to obtain a gradient or relationship.
Put the independent variable on x and dependent variable on y.
A full response labels axes/units, uses a suitable scale and best fit; gradient uses a large triangle and is interpreted with units.
Check whether a result for “Conductors and insulators” is sensible using units, order of magnitude, and a limiting case.
A check should not merely repeat the same calculation.
A full check confirms dimensions/units, compares expected magnitude, and tests behaviour when one variable becomes very small or large.
Connect “Magnetic poles” to energy conservation or a force/field model and justify the choice.
Define the system and interactions.
A full response defines the system, describes transfer or interaction, applies the appropriate model, and states losses or limitations.
Write a multi-step exam response about “Magnetic fields” with calculation and evaluation.
Separate givens, model, calculation, result, and evaluation.
A full response includes an appropriate diagram/model, laws, algebraic rearrangement, SI substitution, suitably precise result, and evaluation of assumptions.
Compare two methods for investigating “Earth, Moon and Sun” and select the more reliable using criteria.
Use accuracy, repeatability, control, and safety.
The choice must use at least three comparable criteria and acknowledge one trade-off or limitation.
