Investigating Resistance Practical

This AQA GCSE Physics required practical examines how factors like wire length, thickness, and temperature affect electrical resistance.

Key apparatus includes:

  • Voltmeter to measure potential difference
  • Ammeter to measure current
  • Power pack as electricity source
  • Meter stick to measure wire length

Students calculate resistance using:

Resistance = Potential difference / Current

Highlight: Key findings include longer wires having more resistance, thicker wires having less resistance, and higher temperatures increasing resistance.

Important considerations:

  • Use low voltage to prevent wire overheating
  • Allow wire to cool between readings
  • Check for zero errors on meters

Example: Increasing wire length from 10 cm to 20 cm would approximately double the measured resistance.

This investigating resistance practical GCSE develops skills in controlling variables and analyzing relationships between electrical quantities.

Investigating Electrical Components Practical

This AQA GCSE Physics required practical explores current-voltage relationships for different electrical components:

  • Resistors
  • Lamps
  • Diodes

Apparatus setup:

  • Voltmeter connected in parallel
  • Ammeter connected in series
  • Variable power supply
  • Component under test

Definition: A diode is a component that only allows current to flow in one direction.

Key observations:

  • Resistors show a linear relationship Ohm′slawOhm's law
  • Lamps have increasing resistance at higher voltages
  • Diodes only conduct above a threshold voltage in one direction

Vocabulary:

  • Current: The flow of electric charge
  • Potential difference: Energy transferred per unit charge

This practical helps students understand how different components affect current flow in circuits, essential knowledge for GCSE Physics required practicals Paper 1.

Resistors in Series and Parallel Practical

This AQA GCSE Physics required practical investigates how combining resistors in different configurations affects total circuit resistance.

Experimental setup:

  • Power supply
  • Ammeter and voltmeter
  • Various resistor combinations in series and parallel

Key findings:

  1. Series circuits: Total resistance = sum of individual resistances Adding resistors increases total resistance and decreases current
  2. Parallel circuits: Total resistance is less than the smallest individual resistor Adding resistors decreases total resistance and increases current

Example: In a series circuit with 3Ω and 2Ω resistors, the total resistance would be 5Ω.

Highlight: In parallel circuits, current has multiple paths, leading to lower overall resistance.

This practical develops understanding of complex circuit analysis, crucial for AQA required practicals Physics A Level and beyond.

Students should be prepared to:

  • Explain resistance patterns in different configurations
  • Discuss measurement accuracy and potential sources of error
  • Apply findings to real-world circuit design scenarios

Mastering these concepts is essential for success in GCSE Physics required practicals and forms a foundation for advanced study in electrical engineering and physics.

Specific Heat Capacity Practical

This AQA GCSE Physics required practical investigates the specific heat capacity of materials. Students heat a metal block and measure energy input to determine how much energy is needed to raise its temperature.

Key apparatus includes:

  • Joulemeter to measure energy input
  • Heater to warm the metal block
  • Insulation to prevent heat loss
  • Thermometer to track temperature change

The practical aims to calculate specific heat capacity using the formula:

Specific heat capacity = Energy transferred / Mass×TemperaturechangeMass × Temperature change

Highlight: Insulation is crucial to prevent heat loss to the atmosphere and obtain accurate results.

Common exam questions may ask about:

  • Purpose of insulation
  • Reasons for discrepancies from true values
  • Initial slow temperature increase
  • Measurement resolution and uncertainty

Vocabulary: Specific heat capacity - The amount of energy needed to raise the temperature of 1 kg of a substance by 1°C

This GCSE Physics required practical explained provides hands-on experience with calorimetry concepts essential for understanding thermal physics.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
