| Abstract | Electrical safety is important in industrial work. This article provides considerable detail on how current can pass through different parts of the body and each parameter that can impede or limit the flow of current. Electric currents flowing through a human body can have varying effects, ranging from little or no perceptible effect, to shocking sensation, to possibility of electrocution, depending primarily on the magnitude and the duration of the current flow. The effect of current flow is a function of the applied voltage level, the duration of the exposure, and the resistances or impedances of the body and the other available current paths. A key consideration with energized objects is that, in order for the electric current to flow through the body, one body part must make contact with an energized object or conductor and another body part must make contact with the earth or an object or conductor that provides a path for the current to return to its source. This article supplies considerable detail on how currents can pass though different parts of the body and each parameter that can impede or limit that flow of current. The information presented indicates that the most likely scenarios for a dangerous condition would be that when a person comes in contact with an energized metallic object energized at 120 V and the person is barefoot and the ground is moist or wet as are the persons' hands or feet. Nearly, any other condition such as dry ground, rubber, or leather soled shoes; dry hands and so on have a lower probability of creating current flows that would be considered damaging or disruptive. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
