BEST physics tuition
A-Level Physics Tuition by Award-Winning JC Lectur Most probably the only JC Physics Tutor in Singapore with two Outstanding Contribution Awards by MOE
ELECTRIC FEILD Recall and use Coulomb’s law in the form F=Q1Q2/4(pi)E0r2 for the force between two point charges in free space or air. Recall and use E=Q/4(pi)E0r2 for the field strength of a point charge in free space or air.
ELECTROMAGNETISM Show an appreciation that a force might act on a current-carrying conductor placed in a magnetic field. Recall and solve problems using the equation F = BIL sin(theta), with the directions as interpreted by Fleming’s left-hand rule.
ALTERNATING CURRENT Show an understanding of the principle of operation of a simple iron-cored transformer and recall and solve problems using Ns / Np = Vs / Vp = Ip / Is for an ideal transformer. Distinguish between r.m.s. and peak values and recall and solve problems using the relationship Irms = Io / sqrt(2) for the sinusoidal case.
LASER/SEMICONDUCTOR Distinguish between conduction band and valence band. Discuss qualitatively the origin of the depletion region at a p-n junction and use this to explain how a p-n junction can as a rectifier.
NUCLEAR PHYSICS Show an understanding that an element can exist in various isotopic forms each with a different number of neutrons. Show an understanding of the concept of mass defect.
