Why a UJT is not a thyristor?

Because to remain in conduction it requires a supply of emitter current. Without a minimum value of emitter current it can't stay in the on position. Most thyristors do not require gate current after they are turned on to remain in conduction


What is 16 awg wire rated for?

16 AWG wire is typically rated for a maximum current of about 3.7 to 10 amps, depending on the installation conditions and the type of insulation used. For power transmission in residential applications, it is often used for low-power devices and lighting circuits. The wire can handle a maximum voltage of around 300 volts in most cases. Always consult local electrical codes and regulations for specific applications and safety requirements.


What is the peak value of current if its rms value is 2A?

If an AC current is sinusoidal, then the peak value of a current with an RMS value of 2A is 2.8A, or 2A times the square root of 2.However, very few current waveforms are sinusoidal. In fact, they are often far from sinusoidal - they are more often pulsating - because most power supplies, even switching power supplies, only draw current when the rectifier diodes conduct to recharge the primary filter capacitor. That only occurs once (half wave rectifier) or twice (full wave rectifier) each line cycle.The square root of 2 rule does apply if the load is purely resistive and the voltage is also sinusoidal. Most voltages are also not sinudoidal, because of the pulsating current issue, and because conductors are not perfect zero impedance conductors. Voltage waveforms, however, are more closely sinudoidal than current waveforms.The most accurate way to measure the peak current value is to observe it with an oscilloscope. If you want the analytic approach, you need to back calculate from peak value to RMS value, knowing that RMS value is the square root of the sum of the squares of the observations divided by N, as delta T approaches zero, and N approaches infinity. (Best to just use the oscilloscope.)


Why shunt resistance used in ammeter and why is it connected in parallel?

An ammeter's coil requires very little current for full-scale deflection (fsd). So, to measure a current above its fsd value, most of that current must be allowed to bypass the coil. This is achieved by placing a very low value shunt resistance in parallel with the coil ('shunt' is an archaic word for 'parallel').


What is the resistance range of a 100k ohm potentiometer?

from a very low value of resistance relating to the contact of the wiper material ; approx .. 0.08 ohms / which would be negligable in most circuits . to a maximum value of 100 000 ohms , nominal , directly connected but this depends on tolerance rating or resistor ; maybe 2.0 % ? so varation = 2/100 x 100 000 = 2,000 . depending on tolerance quoted by manufacturers ; 100 000 + 2,000 = maximum = 102,000 ; or a lower value = 100 000 - 2, 000 = 98 ,000 .. so the range could be anywhere between 98,000 and 102,000 maximum . and minimum = approx, 0.08 ohms.

Does diode flow current in reverse bias?

Diodes will have a small leakage current in reverse bias. In most cases, this current can be considered insignificant and ignored.


What is the mode the maximum minimum and the range?

The mode is the value that appears most frequently in a data set. The maximum is the highest value, while the minimum is the lowest value in that set. The range is calculated by subtracting the minimum from the maximum, indicating the spread of the data. Together, these measures provide insights into the distribution and variability of the data.
