How do you find the probability of a normal distribution given the mean and standard deviation? Conclusion. In a normally distributed data set, you can find the probability of a particular event as long as you have the mean and standard deviation. With these, you can calculate the z-score using the formula z = (x […]

What is the difference between emitter and collector? The main differences between emitter and collector are doping concentration and size. The emitter is heavily doped, while the collector is lightly doped. You could try to swap them, but you’ll get a very low HFE, probably even less than 1. How will you identify the base […]

What would happen if you got too close to the center of the Milky Way galaxy? The closer you get to the heart of the galaxy, the tighter stars are packed together. Because of this high star density, the Earth would be blasted with a lot more radiation than what the Sun throws at you […]

How do you program a random number generator? Example Algorithm for Pseudo-Random Number Generator Accept some initial input number, that is a seed or key. Apply that seed in a sequence of mathematical operations to generate the result. Use that resulting random number as the seed for the next iteration. Repeat the process to emulate […]

What range is displayed on a high pressure gauge on a service manifold? 0 to 500 psig What color is the low pressure gauge on a typical gauge manifold set? blue What units does a compound pressure gauge for the low side of the system measure pressure in? The compound gauge measures low pressure (psig) […]

What is search in C? Linear search in C to find whether a number is present in an array. If it’s present, then at what location it occurs. It is also known as a sequential search. It is straightforward and works as follows: we compare each element with the element to search until we find […]

What is the difference between the spring type clutch and diaphragm clutch? (e) The diaphragm acts as both clamping spring and release-finger. (g) Clamping load in diaphragm-spring is independent of the engine speed whereas coil springs tend to bend along their length and loose their thrust at high speeds. (h) In this clutch disengagement pressures […]
