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. |
