Applied Science AQA/Resistance and Resistors
Topic Title[edit | edit source]
Setting Applied context[edit | edit source]
It is useful to have studied this topic before doing the Unit 2 resistivity portfolio.
|Syllabus Content||What you need to do|
|• calculating the total resistance of a circuit which contains resistors in series, resistors in parallel and a combination of both
• the formulas:
R total = R1 + R2 + R3
1/R total = 1/R1 + 1/R2 + 1/R3
• uses of potential divider circuits
|• free electrons and the electrical behaviour of conductors and semiconductors
• the effect of temperature on the resistance of conductors and semiconductors
• the behaviour of thermistors and light-dependent resistors (LDRs)
|• graphs of V against I to find resistance
• graphs of voltage against current for a range of components including standard resistors, thermistors and lamps.
Exploration of key ideas (must be original text, not C&P) – level checked by AQA[edit | edit source]
In general, point students towards the approach to take, as opposed to just giving them information.

Careers and Organisations[edit | edit source]
Carry out some research into these jobs in this area. (Feel free to add other jobs you find.)
|Research these roles:||What are the benefits of this role to society?||What organisations would employ someone in this role?
(Where would they work?)
|What would someone in this role have to do within the organisation?||What scientifically-related skills do they need to have?
What techniques do they need to have mastered?
|What experience is needed to undertake this role and its responsibilities within an organisation?||What other science personnel will they work with in their organisation.|
