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.

∙ 10y agoVoltage is present even if there is no current flowing. For example, a power line that is disconnected at the load end is still energised: no current is flowing, but the line conductors are still energised at high voltage. So, as far as power lines are concerned, it's the voltage that's the danger. Furthermore, current is dependent on voltage; making contact with a high-voltage conductor will likely result in a horrendously-high current through your body.

When does the electric current flow?
An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).
Is units of electric current a volt?
Electric current is measured in amps not voltsElectric voltage is measured in volts.
What is usually carried on a pylon?
High Voltage Electric Current.
How do we calculate voltage?
V = I x R V = voltage, I = Current, R = Resistance or it can be calculate like this V = P / I V = Voltage, P = Electric Power, I = Current
High voltage by itself does not produce electric shock What does?
The amount of current passing through your body and the path of the current.
What is the formula of electric current?
the formula for electric current is VI ,where v is voltage then I is the current. the unit used for current is ampere and volts for voltage. multiply the total I to the Voltage The formular of electric current is given by I=V/R ,I=P/V
What causes a electric current in a electric circuit?
Voltage causes current to flow in an electric circuit.

What causes a current in an electric circuit?
Voltage causes current to flow in an electric circuit.
What is the difference in the current and voltage?
Current (amperes) is the rate of flow of electric charge, in coulombs per second. Voltage, on the other hand, is the electric potential of that charge, in joules per coulomb.Current and voltage are related to resistance by Ohm's Law, which states that voltage is equal to current times resistance.There is a tendency to misuse the term "current", and to apply it, for instance as "an electric current of 120 volts". This usage is incorrect. Current is current, and voltage is voltage, as noted above.
Is an electric voltage a varying electric current that reprsents information?
false
Who is resposible voltage or current for electric shock?
It is impossible to separate the two. The voltage determines the magnitude of the current, and the current causes the damage. So, they are both responsible for electric shock.
Is emf current greater than current?
EMF is electromotive force. It is another name for voltage. Voltage is electric potential in joules per coulomb. Current is electric flow, in amperes. Amperes are coulombs per second. Voltage and current are not the same thing, and "emf current", or "voltage current" does not make sense.
Is units of electric current a volt?
Electric current is measured in amps not voltsElectric voltage is measured in volts.
What is a device that changes electric current into a different voltage?
Nothing can change electric current to voltage. You can compare "current " to rate of flow, while "voltage" is the energy level. Transformers can be used to increase or decrease the voltages of alternating current as is done from 'street power' to domestic power.
Why electric current across a wire drops?
Electric current does not drop. Electric voltage, however, drops across a wire because the wire has non-zero resistance. (Do not confuse electric current with electric voltage - they are not the same.)The reason current does not drop is that, in a series circuit, according to Kirchoff's current law, the current at every point in a series circuit is the same.
