Ethernet Cable – Color Coding Diagram
The information listed here is to assist Network Administrators in the color coding of Ethernet cables. Please be aware that modifying Ethernet cables improperly may cause loss of network connectivity. Use this information at your own risk, and insure all connectors and cables are modified in...
Diodes – Introduction
Introduction to Diodes
Diodes are polarised, which means that they must be inserted into the PCB the correct way round.
This is because an electric current will only flow...

I would like to recommended to all beginner electronic hobbyist that would like to shape their skill on repairing electronic component or checking for troubleshooting any electronic appliances to try this above and below ebook..
This ebook explain all the required step and the...
Transistor Emitter Capacitor Short Circuit Tutorial
The emitter is connected to zero volts and there is an increased emitter/base forward bias.
Base and collector currents increase.
There is more current through R1, a higher ...
Transistor Lower Base Bias Resistor Open Circuit Tutorial
There is no potential divider action and the full +9 volts is applied to the base by R1.
This causes a high base current to flow, which in turn causes a high collector current to flow....
Transistor Upper Base Bias Resistor Open Circuit Tutorial
With R1 o/c there is no voltage on the base, no base bias and no base current.
The transistor is OFF and there is no collector current and no voltage drop across R3.
The collector voltage ...
Transistor Emitter Resistor Open Circuit Tutorial
Posted under Intermediate on Tuesday, 9 September 2008 by Zaid
There can be no base or collector current.
Since the current through R1 is less than normal, there will be a lower voltage drop across it and the base voltage will be higher than...
Transistor Collector Load Resistor Open Circuit
Posted under Intermediate on Tuesday, 9 September 2008 by Zaid
The base is still forward biased, so base current flows.
The base current will be higher than normal, because all the emitter current goes to the base and none to the collector.
