The Potential Divider Rule Determining the relative brightness of light bulbs using the potential divider rule How Internal Resistance affects brightness of light bulbs
How emf is induced Electromagnetic Induction and its Effects To explain a phenomenon that happens due to Electromagnetic Induction, we can use an acronym CFILE to structure our answer. C stands for cutting of flux or changing of flux linkage. This is necessary for electromagnetic induction to happen. When a wire is pulled through a
A video tutorial on the use of the Addestation datalogger with its motion sensor to measure the displacement of a bouncing ball and to observe the velocity and acceleration using its differentiation function.
The root-mean-square value of an alternating current is equivalent to the steady direct current that would dissipate heat at the same rate as the alternating current in a given resistor. For a sinusoidal source, (a) the root mean square value of the current is given by . (b) the mean or average power < P
[accordions autoHeight='true'] [accordion title="1. Particle Nature of Light"] A photon is a quantum of electromagnetic radiation. The energy of a photon is given by E=hf, where h is Planck's constant (6.63 10-34 J s) and f is its frequency. [/accordion] [accordion title="1.1 Photoelectric Effect"] The photoelectric effect is the emission of electrons from a metal surface when electromagnetic radiation of sufficiently high frequency
This video tutorial is a guide for next week's practical for CG18/12.
The Nucleus existence and size demonstrated using the Rutherford -scattering experiment. consists of nucleons (protons and neutrons) isotopes of an element share the same number of protons but different number of neutrons. Nuclear Reactions nuclear reactions involve two or more reactants. represented using the form: for a reaction that releases energy, mass-energy of reactants =
LASER This flow chart shows the requirements expected of students when describing how light is produced using LASER (Light Amplification by Stimulated Emission of Radiation). BAND THEORY Energy bands are formed in solids where there are multiple atoms, each closely packed with their neighbouring atoms. The outer electrons of each atom interacts with those
