Is water a conductor or a insulator of electricity?
Pure water is an insulator. Only impure water, ie. water that contains ions, will conduct electricity, as to why H2O does not break into the H ions and OH ions and then conduct electricity, to be honest, I don't yet know. But I suspect that the electrons flowing through are not vibrating at the correct frequency to excite the electrons that hold the two ions together to break apart.
Is force required to break virgin?
M ganna say yes 2 that because in some of the cases we required force to Break virginity. Most of the girls dnt show up easily to breake virginity. But in my case I did it.
All other things being equal why is it harder to break a shorter piece of wood than a longer one?
When you break a plank the length of plank from the break point to the nearest end acts as a 'leaver' the longer the leaver the greater the mechanical efficiency. Therefore a long plank will be easier to break (provided you try and break it near the middle).
What does break resistance means?
Resistivity is the ability of any metal or conductor to resist the flow of current depending on the diameter of the conductor.Electric fuse is an alloy with low resistivity and breaks when the resistance is high.This is the point of break resistance. Literary meaning of break resistance would be an act of greater force to break any opposing force as a breakthrough the defence.
How do you calculate the minimum speed a tennis ball has to go to break tempered glass?
I don't think this can be calculated exactly. Whether the glass will break will depend not only on the speed of the tennis ball, but also on its mass and size, its hardness, the thickness and quality of the glass, and perhaps even luck.
Break down voltage?
The breakdown voltage of an insulator is the minimum voltage that makes it partially conductive electrically. On the other hand, the breakdown voltage in a diode refers to the minimum reverse voltage to cause it to conduct in reverse.
Which voltage is greater in thyristor whether forward break over or reverse breakdown voltage?
It is stated that one of the voltage is greater in thyristor whether it be forward breakover or reverse breakdown voltage. It is also stated that the greater of the 2 voltages in thyristor is the forward breakover voltage.
Which is greater the breakdown voltage or the barrier potential?
Breakdown voltage is far greater than barrier potential. silicon:- break-down voltage :- 5v - 450 v barrier potential ;- 0.5v to 0.7 V
Is fwd break over voltage is greater than reverse breakdown voltage i.e VboVbr?
forward breakover voltage is slightly smaller than reverse breakdown voltage
What is guard ring?
A guard ring is a circular conductor located near the bottom of a high-voltage insulator string, from where the line conductor or conductors are suspended. It's function is to evenly-distribute the potential gradient across the length of the insulator string, by preventing the concentration of electric field in the vicinity of the line conductor, which would otherwise act to break down the insulating properties of the insulator chain.
Why lightning arrestor should be placed near transformer?
A lightning arrestor acts to reduce a voltage surge due to, for example, a lightning strike on a power line. This will protect the transformer from an over-voltage acting to break down its resistance. A lightning arrestor is connected between each line conductor and earth. Under normal voltage conditions, it acts as an insulator, but when a critical value of over-voltage is reached, it conducts -suppressing the voltage spike.
Triac break over voltage?
A: TRIAC will break over and conduct at a certain if a certain voltage is reached. That voltage depends on all different triacs devices
Does paper conduct electricity?
At low voltages (<100V) paper is an insulator. At HT potentials (>1000V) the paper will break down as an insulator and start to conduct.
What is the break down voltage point for a zenerdiode?
The breakdown voltage point for a Zener diode is 17 volts
When there is a break on the circuit what is the reading?
The typical answer is current is zero when there is a break in the circuit. It depends on the complexity of the circuit, there may be other paths for the current to flow, such that if there is a break in one part of the circuit, the rest of the circuit still has current flow (but a different value than designed). If you are reading voltage, and there is a break then that will change, also depending on the complexity. If it is a single loop, and you're reading voltage before the break, your voltmeter will read the same voltage as the voltage source, since there is no current flowing between any resistors between the meter and the source. If you're reading voltage after the break then the meter will read zero (0) volts.
Is Bakelite an electrical conductor?
All materials can conduct some electricity. Bakelite, by Westinghouse, is considered an insulator in ambient conditions because it has specific resistivity in the range of many megohms per unit volume. Depending on the physical shape of the Bakelite and the amount of voltage impressed upon it, Bakelite may break down (loose its insulating properties). Under normal industrial conditions Bakelite is considered an insulator.
When do reactions that release energy happen?
The release of energy (exothermic reaction) happens when the energy release by forming the products of the reaction is greater than the energy required to break the bonds of the reactants.
