If diode is connected to two voltage sourceone in forward biased other biased diode in rewrse what will be net effect of two source on diode?
If a diode is connected with two voltage sources for ex: One is 5V in F.B and The other is 3V in R.B then the Effective voltage will be equal to 2V F.B. So, The diode conducts.
What are the semiconductors in the periodic table?
Semiconductors can either be intrinsic or extrinsic. Intrinsic semiconductors are elements that are in their pure form. These will usually have positive and negative sides because the electrons migrate towards one direction. On the other hand, extrinsic semiconductors are when the conductivity (or ability to make an electric charge with the electrons) are controlled by adding other atoms. These atoms that are added are called dopants. Dopants donate or receive electrons from the semiconductor to make impure.
What does diode mean in a science?
A diode is an electronic component with the characteristic that its resistance is not constant, but depends on the magnitude of the current through it. An ideal diode has zero resistance to current in one direction, and infinite resistance to current in the reverse direction.

Formula for peak inverse voltage?
In full wave rectifier peak inverse voltage is not present. Since both the half cycles are conducted successfully. Peak inverse voltage is one which is the available voltage across the rectifier ( diode) when it was not conduction. ANSWER: The diode reverse breakdown voltage should be the AC peak to peak . Example the secondary is 100 AC then the diode should be rated to 282 volts minimum for each.
What parameter in a germanium diode differs from those in a silicon diode?
A germanium diode has a lower forward voltage drop compared to a silicon diode, typically around 0.3V for germanium and 0.7V for silicon. Germanium diodes also have a higher reverse current leakage compared to silicon diodes.
What is the difference of silicon diode and germanium diode?
A silicon diode has a voltage drop of approximately 0.7V, while a germanium diode has a voltage drop of approximately 0.3V. Though germanium diodes are better in the area of forward voltage drop, silicon diodes are cheaper to produce and have higher breakdown voltages and current capabilities.
Is 1N4007 OA79 silicon or germanium diode?
The entire 1N40xx series of power diodes are all silicon. The OA79 small signal diode is germanium.
What is the difference between a silicon diode and a germanium diode?
The silicon diode (unless its a Schottky diode) conducts at approximately 0.6 volts. The germanium diode, however, conducts at a much lower voltage, typically 0.2 volts. This means that the germanium diode is better at small signal rectification applications, such as AM radio detectors, allowing a smaller tuner tank circuit.
What is the difference between a silicon diode and germanium diode?
Silicon diodes have a higher forward voltage drop (~0.7V) compared to germanium diodes (~0.3V). Silicon diodes have higher temperature stability and are more commonly used in modern electronic devices, while germanium diodes are more sensitive to temperature changes and are less commonly used.
What is more referred to use si diode or a ge diode?
silicon diode is preferred more when compared with germanium diode because in silicon diode the operating voltage is 0.7v where as in germanium diode the operating voltage is 0.3v , germanium is temperature sensitive so it can be easily destroyed by increasing temperature hence silicon diode is preferred more
What is the temperature of germanium diode compare to silicon diode?
Germanium diodes typically have a lower forward voltage drop than silicon diodes, which can result in slightly higher temperatures under the same operating conditions. However, the difference in temperature between the two types of diodes is generally minimal and may vary depending on the specific application.
What is O in oa79 diode?
In general O in diodes stands for germanium.since OA79 is a germanium diode O stands for germanium
What is the Difference between Si and Ge diodes?
The significant operational difference between a Si diode and a Ge diode is that Si diodes have a knee voltage of 0.7V needed to allow current flow and Ge diodes have an operational voltage of 0.3V to allow current flow.
Why Si is used than Ge in semiconductor diode?
silicon diodes Cut in voltage is 0.7 V.but the Germanium cut in voltage is 0.3 V that's why .............
If diode is silicon metal then potential difference is 6V and if diode is germanium metal then potential difference is 2V why?
Silicon diodes usually have a voltage drop of .6-.8 volts across them before they will fully conduct. Germanium diodes are usually in the range .5-.6 volts I believe. The voltages you're quoting seem strange - if you can give the setup you're using to measure this, and the part # of the diodes you're using, a better answer can be given. As it stands, I have to ask if you're measuring correctly.
Germanium diode works at 0.3v?
To forward bias a germanium diode you need to reach between 0.2 and 0.3 V between anode (+) and cathode (-). Once this voltage is reached, the diode will conduct. Make sure you have a resistor to limit the forward current to a safe (for the diode, that is) value.
