Electricity is transferred with high voltage and low current to reduce transmission loss ( I2R , where R= resistance of wire).
As high voltage is present in transmission lines, Danger-high voltage is written.

What is wrong with the sign of danger high resistance?
The sign "Danger: High Resistance" is misleading because it implies that high resistance is inherently dangerous, which is not accurate. In electrical terms, high resistance typically means less current flow, which can reduce the risk of electric shock. Instead, signs should emphasize the dangers of high voltage or low resistance, which can lead to increased current and potential hazards. Clarity in safety signage is crucial to effectively communicate risks and ensure proper precautions are taken.
How are the plus and minus voltage signs determined for resistors?
Resistors have no polarity. The voltage across a resistor is determined by the direction of current flowing through that resistor (and vice versa).
Can kirchoff's voltage law be used to determine voltage drop?
Yes. Kirchoff's Voltage Law states that the signed sum of the voltage drops going around a series circuit is zero. Thus, if you know all but one, you can figure it out. You simply add what you know up, and what is left is the last drop. Don't forget to be consistent in your use of signs. If, for instance, you show a voltage or current source as a voltage rise, then it must be considered to be a negative voltage drop. Or vice versa, as the case may be.
Does the neon power supply for those beer signs in bars output high voltage AC or DC?
High Voltage AC.
How many amps in 8 ohm using ohm's law?
You must know the applied voltage to determine the answer. According to Ohm's law: I = E/R (current equals voltage divided by resistance) So, if the voltage were, say, 16 volts, then the current through the 8 ohm resistor would be two amps: 2 = 16 / 8
Why do signs read Danger-High Voltage rather than Danger-High current?
Electricity is transferred with high voltage and low current to reduce transmission loss ( I2R , where R= resistance of wire). As high voltage is present in transmission lines, Danger-high voltage is written.
Why during measurement the measured voltage and currents have negative sign?
Because of the polarity of the circuit. The signs of measured current and voltage depends on the direction of the current and voltage.
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.

How does tha current flows in the circuit?
Most people agree that current flows from the negative (cathode) terminal of the voltage source, through the load, and back to the positive (anode) terminal of the voltage source. This is because it is accepted that current is a flow of electrons. However, most analyses techniques use the convention that current flows from anode to cathode. It is simply a convention. So long as you are consistent in your usage of signs, you will be OK.
What is the purpose of traffic signs?
to warn of a possible danger ahead.
What are the signs your wife is gay?
There are no reliable signs, ask her instead.
What shape is a danger sign on a French highway?
Danger signs are always triangular, on any roads and motorways in France.
Why are warning signs red instead of blue?
Red is often used for warning signs because it is a color that naturally grabs attention and is associated with danger or emergency situations. Blue, on the other hand, is more commonly used for informational or regulatory signs to convey a sense of calm and authority.
