What is short circuit?
A short circuit is an electrical circuit that allows a current to travel along an unintended path with no or a very low electrical impedance. Electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied.
Why putting the cold bottle in a room temperature it’s misted over?
There is moisture in the air; this is often called "humidity". The amount of moisture that can be in the air depends on the temperature of the air. The warmer the air is, the more water it can hold in it.
When the air comes up against the cold outside of a cold bottle, the air to the bottle gets cold first. It gets so cold that it can't hold as much water anymore and some of the water "condenses" or comes out of the air onto the bottle. This process is similar to what causes clouds to form and rain to fall. Moisture in the air is condensed and precipitated because of cooler temperature or similar effect. The formation of dew is almost exactly like the formation of the water droplets on the outside of a cold bottle.
Frost is the coating or deposit of ice that may form in humid air in cold conditions, usually overnight. Frost forms when the temperature of a solid surface in the open cools to below the freezing point of water and for the most clearly crystalline forms of frost in particular, below the frost point in still air. In most temperate countries such temperatures usually are the result of heat loss by radiation at night, so those types of frost sometimes are called radiation frost.
What is siphon?
Siphon is a tube used to convey liquid upwards from a reservoir and then down to a lower level of its own accord. Once the liquid has been forced into the tube, typically by suction or immersion, flow continues unaided.
Application of siphon:
Siphon can be described as a tube or pipe that allows liquid to flow from the higher level to the lower level. Siphon allows liquids to flow uphill, above the surface of the tank or reservoir, without pumps. Liquids flow down the tube under the pull of gravity.
What is the working principle of a Siphon?
Siphon works because of gravity. The gravity pulling down on the taller column of liquid causes less pressure at the top of a siphon.
The mass of water entering the tube and flowing upward is equal to the mass of water flowing downwards and leaving the tube. A siphon draws the liquid out of the reservoir until the level of the tube or pipe falls below the intake of the liquid. It continues to work until the outlet of a siphon equals the level of the reservoir.
How does a Siphon work?
What are the uses of Siphon?
Siphon is used in many day-to-day applications. It is useful in keeping unwanted impurities out of liquids. Siphoning can prevent impurities from being transferred to a fresh container. Siphoning is therefore useful in the fermentation of wine and beer.
Irrigated fields often use siphon to pull in water from nearby ditches or channels into their fields. Siphon can be used in flooded homes or cellars to remove accumulated water.
Large siphons are used in municipal waterworks and industries. They are controlled using valve inlet and valve outlet.
A siphon is also used to clean a fish tank or aquarium.
C1 attenuates components of the input signal from about 20 Hz down, and completely blocks DC. You might want something similar on the output of the amplifier. Whatever is downstream may not want to deal with the 6V or so DC offset this amplifier puts on the signal, and may have its own bias requirements. In a audio amplifier, or anything else that doesn't need to work at DC, it is common to have capacitors between stages to block DC and allow each stage its own DC operating point.
A capacitor blocks DC, so it can be used to pass a signal (e.g. audio, etc) without it's DC level interfering with the DC bias of a transistor. This way the DC offset of the input signal can be at any level and the transistor amplifier will treat it the same way.
For example, if you have one transistor with it's collector output at a DC level of 5V, and the next transistor stage has it's base biased around 1V, directly connecting them would turn the second stage full on all the time as the input voltage will always be too high.
If we add a capacitor in between the stages, one side can be at the 5V DC level, and the other side can be at the 1V level, and only the AC variations pass through. This way the second stage operates correctly.
Petrol tanker truck is fitted with an iron chain kept hanging and touching the road. Why?
Fuel trucks are supplied with a chain or strap to discharge static electricity; this is because natural rubber tires manufactured generates a powerful static charge on the chassis of the vehicle which caused numerous fires during fuel transfer operations.
Modern synthetic rubber tires actually have enough carbon in the rubber compounds that they conduct enough electricity that any static charges are dissipated back to the road surface directly through the tires now; therefore there is no longer any need for a dissipation strap or chain.
