GCE A-Level Physics Syllabus
Chapter 15: D.C. Circuits
Circuit symbols and diagrams
Series and parallel arrangements
(a) Recall and use appropriate circuit symbols as set out in the ASE publication Signs, Symbols and Systematics (The ASE Companion to 16–19 Science, 2000).
(b) Draw and interpret circuit diagrams containing sources, switches, resistors, ammeters, voltmeters, and/or any other type of component referred to in the syllabus.
(c) Solve problems using the formula for the combined resistance of two or more resistors in series.
(d) Solve problems using the formula for the combined resistance of two or more resistors in parallel.
(e) Solve problems involving series and parallel circuits for one source of e.m.f.
(f) Show an understanding of the use of a potential divider circuit as a source of variable p.d.
(g) Explain the use of thermistors and light-dependent resistors in potential divider circuits to provide a potential difference which is dependent on temperature and illumination respectively.
(h) Recall and solve problems by using the principle of the potentiometer as a means of comparing potential differences.
