Diodes do not have color codes as far as I know. The "turn on" voltage is usually in the ballpark of .4 - .8 volts, and is dependent on the type of diode (germanium, etc.).
You may be referring to resistors. Look up in Google resistor color code, and this should help you. There will be three colored lines, two are the resistance, the third is a scaling factor.
For example, if the first two colors match 82, and the third matches 3, the resistor is a 82 x 1000 = 8.2k ohm resistor.
There may also be a fourth color; this denotes the resistance tolerance (1, 2, 5, or 10 percent). If the tolerance is 10%, the above example may range from 8.2k + / 1 820 ohms.

What is the physical length of a voltage waveform?
Voltage does not have a waveform. The waveform is based upon the frequency of the voltage or current. A battery (any voltage) does not waveform, however the voltage coming into your house (US) has a frequency of 60 Hz. The length of the 60 hz waveformLength (in centimeters) = (3 x (10 ** 10))/ Frequency in hz =500 000 000 cm
How do you calculate voltage drop in a parallel circuit?
The formula for a simple DC voltage drop across a cable is:VDrop = Vmeasured at the input of cable - Vmeasured at the output of cableThis formula may seem simplistic however keep in mind that the sensitivity, accuracy and resolution of measuring instrument instrument is what is really important.If you know the DC current flowing through the cable and the impedance of the cable then you can use Ohm's law. Vdrop = I R where Vdrop is the voltage drop across the cable in volts I is the current flowing through the cable in amperes R is the resistance of the cable in ohms.ADDITIONALCalculation of the voltage drop is given by the formula belowVoltage Drop (Volt) = [(mV/Am)/1000] * I * lWhere mV/Am = millivolt drop per meter per ampere of the cable(this information is given in the table based on IEE Wiring Regulation)I = Current in the cable (in Ampere)l = Distance of cable (in Metre)See related links below
What is the Iroquois national colors?
"They didn't have a color, they used all the colors they had.Also,they didn't like a sertent colors." Incorrect. The national colors of the confederacy of the Haudenosaunee, ak the Iroquois, ak the 6 nations is purple/blue and white. Their flag is actually based off the Hiawatha belt. This is just for the Confederacy, each of the 6 nations has their own symbols and colors along with each clan within each nation.
Is precious based on a true story?
no, it is based on a novel written by a former literacy teacher, the character however is based on a compssite of women that the teacher came across, so although the story itself is nto true perse the events that take place within sadly are.
How does a voltage divider work to distribute voltage across multiple components in a circuit?
A voltage divider is a circuit that uses resistors to divide the input voltage into smaller voltages across multiple components. This is achieved by connecting the resistors in series, creating a voltage drop across each resistor based on their resistance values. The output voltage across each component is determined by the ratio of its resistance to the total resistance in the circuit.
What is transistor as a switch?
transistor is a nonlinear device. it will acts as a swicth based on the cut in voltage we can easily identifying the the transistor is in forward or reverse bias.in forward it is 'on' reverse bias 'off'.
What are performance parameters of rectifier?
Rectifiers have two parameters of interest - maximum forward current - and maximum reverse voltage. A rectifier is generally chosen based on these two parameters. Other parameters include turn-on/turn-off time, forward voltage drop, and capacitance. The importance of these and other parameters depends on the circuit design requirements.
When resistors are connected in series in a circuit. what are the relationships between the voltage drops across the resistor and the currents through the resistors?
When resistors are connected in series in a circuit . the voltage drop across each resistor will be equal to its resistance, as V=IR, V is direct proportional to R. An A: The relationship is that the current will divide for each paths in a parallel circuit and the voltage drop across each will be the source voltage. In a series circuit the current will remain the same for each component but the voltage will divide to reflect each different component value. And the sum of all of the voltage drops will add to the voltage source
What is relation between voltage and temp?
The relationship between voltage and temperature can vary based on the material or device in question. In general, an increase in temperature can lead to an increase in resistance, which in turn can affect the voltage drop across a circuit. It is important to consider the specific characteristics of the material or device when analyzing the relationship between voltage and temperature.
What happens when two or more capacitors are connected in series across a potential difference?
When two or more capacitors are connected in series across a potential difference, the total capacitance decreases and the total voltage across the capacitors is divided among them based on their individual capacitances.
What is the forward voltage of a silicon based zener diode?
It would be 0.7V, the same as any other silicon diode; except for one thing, most zener diodes are manufactured with a reversed diode in series with them. When the zener is operated in its normal zener breakdown mode this reversed diode conducts, letting the zener operate. When the zener is operated in its forward biased mode this reversed diode prevents conduction. Thus most zeners have no forward voltage.

Why are The colors On the color wheel the way they are?
The colors on a color wheel are arranged based on the way the colors relate to each other. Green is between Blue and Yellow because it is halfway between those two colors. Red is across from Green because they are opposites.
What are the various uses of diode?
Most people think of diode as a rectifier. Fair enough, it is because an ideal diode is taught to be a rectifier. In fact most people like the ideal diode characteristic; but dislike the non-ideal characteristics of diodes. However, some of the important inventions of our time are based on non-ideal characteristics of the diode. Below are a couple of samples: 1) Temperature sensor. A diode voltage changes with temperature. Assuming a fixed current going through the diode in the forward biased region, and the current is low enough that the diode resistance does not affect the voltage, the forward voltage has a negative temperature coefficient of about -2mv/degreeC. Once the temperature and voltage relationship is characterized with a fixed current, one can tell easily the temperature from the reading of the forward voltage. 2) Bandgap reference and regulator. This is related to temperature sensing as well. Since diode voltage has a negative temperature coefficient, a positive temperature coefficient voltage component added to the diode forward voltage would make an excellent stable voltage reference; a voltage that is independent of temperature. Turns out, the forward voltage is not only a function of temperature, it is also a function of current. To make life more interesting, the temperature coefficient of the voltage voltage is a function of current. In other words, if you have 2 identical diodes with different current through them, the difference in these two forward voltages also changes with temperature. this voltage is: Vd1-Vd2 = (k*T/q) *ln( I1/I2) where I1 and I2 are currents through the 2 identical diodes. This voltage has a positive temperature coefficient and is directly propositional to T in degrees Kelvin. Utilizing this current, one can amplify and convert it into a voltage, adding this voltage to a diode voltage, you have the making of a bandgap reference. As it turns out, this current is also great for temperature sensor applications.
Can you provide some Ohm's Law practice questions for me to work on?
Here are some practice questions based on Ohm's Law: If a resistor has a resistance of 10 ohms and a current of 2 amperes flowing through it, what is the voltage across the resistor? A circuit has a voltage of 12 volts applied across a resistor with a resistance of 4 ohms. What is the current flowing through the resistor? If a circuit has a current of 0.5 amperes flowing through a resistor with a resistance of 8 ohms, what is the voltage across the resistor? These questions will help you practice applying Ohm's Law to calculate voltage, current, and resistance in electrical circuits.
How do a schottky diode and ordinary pn junction differ in their operation?
The schottky diode is based on a metal-semiconductor junction, called a schottky barrier, that results in lower forward voltage and vastly decreased switching time. While an ordinary silicon diode has a forward voltage around 0.7 volts, with a germanium diode around 0.3 volts, the schottky can be as low as 0.15 volts. The switching time can be in the tens of picoseconds range, compared to hundreds of nanoseconds. The downside is limited reverse voltage rating and poor reverse voltage leakage, which increases with temperature, causing potential thermal runaway.
