1. What are the 4 basic types of electronic components?

Basic electronic components are capacitors, resistors, diodes, transistors, etc. These parts can be powered by a signal generator and a DC power supply. Basic components are used in DIY electronic components.


2. What is the difference between active element and passive element?

Active components have a change in potential and are connected to The Battery. Passive components do not have a change in potential. A resistor is an active component because it reacts to the addition of current (i) by allowing the current to flow through the terminals.  Because of this, a resistor (R) is also known as a blocking device.  The internal element of a diode is able to make or break current flow depending on whether voltage is applied to its terminals (V). 

Active components are electronic circuits that change their outputs when voltage is applied to them.  Passive Circuit components are not changed by the input voltages and output current varies as a function of the input voltage.  Active components add their own power supply, while passive components only take power from other sources.  Active Electronic components get their energy from a battery or other power source. Passive Electronic components use the current going through them to create electricity. The most common type of active component is a resistor, which limits the flow of current through it when voltage is applied to it. A diode prevents one side of an electrical circuit from conducting while letting the other side do so. A capacitor stores energy in its electrodes and then releases it again—it keeps more charge on one plate than the other two plates combined and forces electrons to move in one path as opposed to another, releasing static electricity when connected to an alternating current source. A power supply transforms batteries with steady voltage into higher voltages in order.
