The Transformer Equation A transformer is A device that changes high alternating voltage at low current to low alternating voltage at high current, and vice versa This is designed to reduce ...
Oscilloscope as a DC & AC Voltmeter A Cathode-Ray Oscilloscope (CRO) is a laboratory instrument used to display, measure and analyse waveforms of electrical circuits It can therefore be used as...
Sinusoidal & Root-Mean-Square Current & Voltage An alternating current (a.c) is defined as: A current which periodically varies between a positive to a negative value with time This ...
Required Practical: Investigating Flux Linkage on a Search Coil Aims of the Experiment The overall aim of this experiment is to determine how the magnetic flux linkage varies with the angle ...
Moving Conductors in a Magnetic Field Similar to a coil or a solenoid, a straight conducting rod moving through a magnetic field will also have an e.m.f induced in it This is only when the c...
Faraday's & Lenz's Laws Faraday's Law links the rate of change of flux linkage with e.m.f It is defined as: The magnitude of the induced e.m.f is directly proportional to the rate of cha...
Principles of Electromagnetic Induction Electromagnetic induction is a phenomenon which occurs when an e.m.f is induced when a conductor moves through a magnetic field When the conductor cut...
Magnetic Flux Linkage More coils in a wire mean a larger e.m.f is induced The magnetic flux linkage is a quantity commonly used for solenoids which are made of N turns of wire The flux linka...
Magnetic Flux Electromagnetic induction is when an e.m.f is induced in a closed circuit conductor due to it moving through a magnetic field Examples are a flat coil or a solenoid This...
