Physics Topic: DC Circuits
Recall and use appropriate circuit symbols as set out in the current ASE Report — SI Units, Signs, Symbols and Abbreviations.
Draw and interpret circuit diagrams containing sources, switches, resistors, ammeters, voltmeters, and/or any other types of component referred to in the syllabus.
Solve problems using the formula for the combined resistance of two or more resistors in series.
Solve problems using the formula for the combined resistance of two or more resistors in parallel.
Solve problems involving series and parallel circuits for one source of e.m.f.
Show an understanding of the use of a potential divider circuit as a source of variable potential difference.
Explain the use of thermistors and light-dependent resistors in potential dividers to provide a potential difference which is dependent on temperature and illumination respectively.
Recall and solve problems by using the principle of the potentiometer as a means of comparing potential differences.
[Prac] use ammeter, voltmeter with appropriate scales.
[Prac] use a galvanometer to find the balance point with the null deflection method in a potentiometer.
Note: students offering H1 Physics need not study objectives (6) to (10).
