How electricity affects your body - TestGuy

Mar 10, 2015· How much current flows through a person’s body can be estimated using ohms law (I = E/R).. The average resistance of a dry human body can be as high as 100,000 ohms, of course this varies from person to person depending on their body structure.When wet, the resistance may drop as low as 500 ohms depending on the voltage level.

Current Transformer (CT) - Types, Installation

The knee-point voltage is less applicable for metering current transformers as their accuracy is generally much tighter but constrained within a very small bandwidth of the current transformer rating, typically 1.2 to 1.5 times rated current.However, the concept of knee point voltage is very pertinent to protection current transformers, since they are necessarily exposed to currents of 20 or
