What does bias mean in an electrical circuit?
Bias is a permanent voltage, applied to the input of an amplifier device, in order to make it work in the correct area of an amplification curve. Valves (thermionic tubes) and semiconductors (transistors) both use bias in their grid or base connection. A negative swing in the input could put the control input below the working of the device and cause it to switch off. This is undesirable as it will show as distortion. The bias raises the zero point, so that the signal will not turn the device off.
Why do diede has two resistance values in ieone in forward bias other in reverse bias?
If you are talking about reverse biasing a diode, then you are talking about a zener diode. A zener diode, like a normal diode, has a forward bias around 0.7 volts (depending on current and temperature). Using Ohm's law, you can calculate the effective resistance of the diode in forward bias. (Example: 0.7 volts, 100 milliamps, 7 ohms) In reverse bias, however, a zener diode conducts at a different voltage. This is what zener diodes do. Using Ohm's law, you will get a different effective resistance of the diode in reverse bias, because it is dropping a different voltage. (Example: 5.6 volts, 100 milliamps, 56 ohms) It should be noted that attempting to measure the resistance of a diode does not make sense, because it is a non linear device. You should instead consider the current to voltage curve to understand the diode, be it regular or be it zener.

Why the voltage drop across LED is around 2V instead of 0.7V?
the binary semiconductors used to make LEDs have forward bias voltages from 1.5V to 6V depending on color (1.5V for IR-red to 6V for blue-UV) because the bandgap voltage of the semiconductor is higher than silicon. This higher bandgap is where the photons generated get their energy from. germanium has a lower forward bias voltage of 0.2V because the bandgap voltage is lower. metal-semiconductor contacts, like point contact diodes and schottky barrier diodes, can have forward bias voltages under 0.1V
Where can one find a guide on how to make a webpage?
If you want to create a website it's best to learn HTML, CSS and or PHP first. It's the basics on how to make a web page. If you learned it, you'll automatically be able to create one.
Does bias automatically make an article useless?
Bias in an article does not automatically make it useless. It is important to be aware of bias and consider how it may impact the information presented. Evaluating the credibility of sources, corroborating information with other sources, and critically analyzing the content can help determine the usefulness of an article despite bias.
I know Wikipedia is not always right but how does Wikipedia article writers get the RIGHT info to make an accurate bio on a singer or celebrity?
All information submitted must be sourced. If it isn't wikipedia normally points out that the article may be bias and false.

How can a blind study help reduce bias?
Bias is an impartial judgement. A blind study can help get rid of bias by not letting people make an impartial decision
What factors make for bad sociological research?
Some factors that make for bad sociological research include biased sampling methods, lack of rigorous data analysis, failure to consider alternative explanations, and drawing overly generalized conclusions from limited data. Additionally, ethical violations such as plagiarism, falsification of data, or failure to obtain informed consent can also contribute to poor quality research.
