Magnetic Force on a Current-Carrying Conductor A current-carrying conductor produces its own magnetic field An external magnetic field will therefore exert a magnetic force on it A current-c...
Magnetic Force on a Charged Particle The magnetic force on an isolated moving charged particle, such as a proton, is given by the equation: F = BQv Where: F = magnetic force on the particle (N) B =...
Magnetic Flux, Flux Density & Flux Linkage Magnetic Flux Density The strength of a magnetic field is defined by the density of the magnetic field lines, or magnetic flux density, at that point ...

Exponential Discharge in a Capacitor The Discharge Equation When a capacitor discharges through a resistor, the charge stored on it decreases exponentially The amount of charge remaining on the cap...
Required Practical: Charging & Discharging Capacitors Aim of the Experiment The overall aim of this experiment is to calculate the capacitance of a capacitor. This is just one example of how th...
Charge & Discharge Curves Charging Curves Capacitors are charged by a power supply (e.g. a battery) When charging, electrons are 'pulled' from the plate connected to the positive terminal of th...
Energy Stored by a Capacitor When charging a capacitor, the power supply 'pushes' electrons to one of the metal plates It therefore does work on the electrons and electrical energy becomes stored o...
