What's Left
Disclaimer: What's Left is my own review of concepts not found in paper 3 . That does not mean it will be surely be tested in paper 2 and 1 . It does not include everything that has not been tested due to my limitations. Read my posting at What's Left but make your own decision. Look on the bright side.
What's Left
The force of current or force on charge with formula F = BIL and F = Bqv.
Circular motion is F = mv2/r .
Torque is t = F x perpendicular distance
Force on two parallel current carrying wires. Either attract or repel.
Magnetic flux pattern of straight wire, flat circular coil, long solenoid . Ferrous core increases strenth of B .
How to select velocity of charged particles. Velocity selector.
Define magnetic flux density and the tesla.
If the particle is large like oil drop or dust or soot (not atoms) , gravitational field comes into picture.Be prepared for combined effect of g, E and B . Since E has been ask extensively in paper 2 focus may be on g and B.

The characateristic graph of filament , diode , metallic conductor at constant temperature. .The I-V graph.
The temperature characteristic of the thermistor.
Define e.m.f and potential difference. Distinguish their difference in terms of energy considerations.
Define resistance and the ohm , pd and the volt , charge and the coulomb
The internal resistance of battery, how to calculate terminal pd and power output.
Potential divider and potentiometer
See page 138 Q18
Option A : XY vary from 3V to 6V
Option B: XY vary from 0V to 3V
Option C : XY vary from 3V to 6V
Option D : XY vary from 3V to 6V

Time to go through the sequence of questions you will be expecting. Get ready for next paper.
1. Mechanics - Errors,Vectors, kinematics, forces , circular motion, G-field (maybe),resonance and damping
2. Waves- Stationary, interference (p.d = ...) ,young double slit formula , diffraction grating formula.
3. Electricity and Magnetism - Current electricity, power in circuits, DC circuits, EM , Rectifiers
4. Modern Physics- Photoelectric effect, de broy wavelength, Energy levels, quantum tunnelling, semiconductors (energy band + depletion region ) ,activity and decay constant.
