They assume that logo represents Voltage is most dangerous. but Think again! i dont talk about any the formula. this is about logic. the way how we survive with our limited perception. let me give you some experiments.
Experiment 1 :
i have small battery or flashlight battery or watch battery. do you know how many volt at it? 1.5V, right? is it safe or am i going to die if i touch it? yeah, absolutely safe.
Experiment 2 :
i have an electricity that is used to TV, fan, charging HP & daily life about electonic. do you know how many volt at it? 220V, right? is it safe? absolutely not.
Experiment 3 :
i have something that produces more than 10.000 voltage. lt can be called a Van de Graaff Generator. is it safe or am i going to die if i touch it?
Thus, if you think 220V is dangerous. should a person touch more than 10KVolt? some of you'll think "no as that logo High Voltage". i have a picture that a person touchs Van de Graaf Generator. here it comes :
how about that man? well, he was touching more than 10 KVolt. if you think Voltage is killer. why he wasnt dead? there no make any sense. so, which one is the killer?
you need to understand the relationship between voltage and current. it may be easier if we assume water in a hose. Voltage is equivalent to the pressure at the end of the hose. water flow is equivalent to current and the diameter of the pipe is equivalent resistance. The water in the tank represents charge.
Thus, we get rules :
- The more water in the tank, the more pressure is measured at the end of the hose. ( an increase in charge that causes an increase in Voltage)
- To increase the pressure at the end of the narrower hose, pushing more water through the tank.(an increase in voltage that causes an increase in current. if resistance is constant)
You can have an extremely
high pressure of water in a thin tube but it is not going to do much harm if
you squirt yourself with it as so little water will flow. (Of course, if you
squirt a very small but very high pressure jet on a small area of skin it can
cause some local pain just like a high voltage static discharge can give you a
jolt). But a large hose at a much lower pressure can do much more damage.
The pressure behind the Japanese tsunami was less. The tsunami waves were generally much lower. so, what was the difference? why it become very dangerous? The difference was the flow. so, do you know which one is the killer? yeah, Flow or Current is the most killer. If you have something "high voltage". let you know how much current flows in it. if the current less than 10mA for Alternating Current. it will be safe.
i hope i've made myself clear. it's not baloney. it's science.
