Why is the human body a good electricity conductor?
The human body is a good conductor of electricity due to its high water content, which contains electrolytes that allow electric current to flow through. Additionally, the salts and minerals in the body help conduct electricity. However, while the body can conduct electricity, it is important to note that exposure to high voltage can be dangerous and cause harm.
How capacitor opposes the change in current?
as a voltage is applied across a capacitor charges accumulate on the plates.due to accumulation of charges,electric field between the plates develop in the direction opposite to the applied field.this field give rise to the potential across the plates.if the plates get completely charged due to the applied voltage i.e if the whole of the charge q=c(capacitance of the capacitors)xv(voltage applied) develops on the plates,then the applied voltage wiil be opposed to an extent that no further charges will induce on it.But in practice,it takes very long time for the capacitor to get completely charged due to the applied voltage..............now coming to ac circuits,having capacitor.......if the frequency of ac applied voltage is less then the voltage will change slowly.due to this at each instant large amount of charge will develop on the plates causing large opposition.vice versa to high frequency applied voltage.
Indium Phosphide diode Working?
Indium Phosphide diodes are used as high-frequency microwave and millimeter-wave applications due to their high carrier mobility and low noise. These diodes work by allowing current to flow in one direction when a forward bias voltage is applied and blocking current when a reverse bias voltage is applied, making them useful in high-speed communication systems and radar applications.
The damaging effects of electric shock result from the current that flows in the body.Why then do signs read Danger-High Voltage rather than Danger-High Current?
It is true that the magnitude of current flow through the body determines the effects that occur. The path taken through the body is also responsible for the final outcome. For example the extremities will survive with higher current flow than the heart. There are a lot of factors that effect the magnitude of current flow, body resistance can be one variable. This changes from person to person, and from day to day , as well as conditional. For example wet hands will reduce the resistance to current flow and increase the magnitude of current through the body, dry, dirty hands/skin will have the opposite effect. With all other factors being equal (body resistance, path of current etc) The one variable that will 'push' more current through the body is the voltage level. Low voltage (less than 50V) typically has little effect. Where high voltage such as 4160V dramatically decreases your odds of survival.
High voltage by itself does not produce electric shock What does?
Electric shock occurs when high voltage passes through a person's body, typically when they provide a path for the electrical current to flow, such as through their hand or foot. The severity of the shock depends on factors such as the amount of current and the path it takes through the body.
Why is a high dc voltage applied to a transformer for testing?
A high dc voltage would be applied to test the insulation between the windings.
What will happen to the generator voltage when the load fluctuates in distribution board?
The generator's voltage regulator will sense the fluctuation. If the voltage goes low more current will be applied to the armature to compensate. If the voltage goes high less current will be applied to the armature to compensate.
Why generally the voltage is applied to HV side?
Lower voltages are required if connected to the low voltage side. The testing facility may not have a gen set large enough to test from the high voltage side.
How does electricity shock?
Electric shock occurs when a human body has a contact to the source of voltage that is high enough to cause sufficient current to hair or muscle.
How do you test the 11KV HT cables?
The test equipment used to test high voltage cables is a hi-pot test where a high DC voltage is a applied to the cable. This voltage can be from 150% to 200% of the working voltage of the cable.See related links below.

What are the advantages and disadvantages of such high voltage?
voltage is termed as electrical pressure. when high voltage is applied more is the movement of electrons. hence losses will be less. this is one of the major reason for which high voltage transmission is chosen.secondly due to high voltage the current will be less so as the conductor size
What happens when the voltage applied to a dc motor is suddenly reduced to half its value?
cureent becomes high
How much voltage for 132kv UG cable high voltage testing?
it depends on the specification,,,,,,in saudi arabia as per sec standards 152kv voltage should be applied for a period of one hour.
How charging and discharging of capacitors happened?
in the capacitor they have constant voltage wen supply is given the capacitor get charged(high voltage)and discharge energy wen the voltage is low below the applied voltag.
How come when you use a voltmeter the applied voltage is not equal to the individual voltage of a resistor when it should be because it's in parallel I got 2.5 V in the applied v but only 2 v in each?
There are two possible explanations... The resistance of the applied voltage is sufficiently high, in comparision with the resistors, to cause the resistors to pull the voltage down. The resistance of the voltmeter is sufficiently low, in comparision with the resitors, to cause the voltmeter to pull the voltage down.
Can you produce high voltage in your body without getting a shock?
It is impossible
