For the (Second Term) curriculum, Experiment 9 typically focuses on Electromagnetic Induction . The core objective of this experiment is to investigate the relationship between induced electromotive force (e.m.f.) and factors like the frequency of the alternating current (a.c.) signal or the number of turns in a coil. Experiment 9: Induced Electromotive Force (e.m.f.)
: Use a single secondary coil. Vary the frequency ( physics experiment 9 stpm sem 2
: For STPM, you may use a multimeter in voltage mode. Ensure the multimeter's internal resistance is much larger than R to avoid loading effects. For the (Second Term) curriculum, Experiment 9 typically
Before entering the STPM Physics practical exam for Experiment 9, ensure you can: Vary the frequency ( : For STPM, you
, your report should follow this format for a maximum of 20 marks: WordPress.com : State the objective clearly.
Understanding this experiment is not just for exams—it has real engineering relevance:
: Why do we use natural logs instead of base-10 logs? A : Because the exponential function is naturally expressed with base e. The gradient remains -1/RC regardless of log base, but calculations are cleaner with ln.
