Passive devices Capacitor The capacitor is a passive electronic component with two terminals. Its function is to store electrical energy in an electric field and deliver it to the circuit when needed.

Since electronics and mechanical systems were first developed, the speed at which new materials, techniques and processes have been developed has been rapid and revolutionary. Scientists ...

Active electronics -- components that can control electrical ... can perform the same switching functions as the semiconductor-based transistors used for processing operations in active electronics.

Before the advent of integrated circuits (chips), all electronic components (transistors, resistors, capacitors, diodes) were individually packaged. However, they are still widely used in ...
