The basics of electricity: Basic electricity works like this - When an electric circuit flows through a conductor, a magnetic field (or "flux") develops around the conductor. The highest flux density occurs when the conductor is formed into a coil having many turns. The basics of electronics refer to the concepts that include inductance, capacitance, resistance, voltage and electrical currents. Some of the most commonly used electronic components are resistors, capacitors, inductors, diodes, LEDs, transistors, crystals and oscillators, electromechanical components like relays and switches,...
