Exposure to ELF waves can induce an electric current. Because the human body is conductive, electric currents and resulting voltages differences typically accumulate on the skin but do not reach interior tissues. [22] People can start to perceive high-voltage charges as tingling when hair or clothing in contact with the skin stands up or ...
The antennas contained in mobile phones, including smartphones, emit radiofrequency (RF) radiation (non-ionizing "radio waves" such as microwaves); the parts of the head or body nearest to the antenna can absorb this energy and convert it to heat or to synchronised molecular vibrations (the term 'heat', properly applies only to disordered molecular motion).

The photo also shows an unrelated distribution transformer, which reduces 4160 V to 240/120 V. Closeup of overhead powerline sensor hanging from one phase of a 4160 volt powerline. In the photos on the right, an antenna on the sensor transmits data to a communication device attached to a nearby utility pole.
Shock danger may be reduced by use of an extra-low voltage electrical system that is unlikely to expose a human to dangerous levels of current. Special isolated power systems may be used in applications such as operating rooms, where electrical equipment must be used in proximity to a person unusually vulnerable to electrical shock.
The barehanded approach has a live line worker performing the work in direct electric contact with live parts. Before contact, the worker's body is raised to the same electric potential as the live parts, and then held there by electric connection, while maintaining suitable isolation from the surroundings which are at different potentials ...
The head of Southern California Edison said Wednesday that winds blowing in Eaton Canyon on Jan. 7 were not strong enough to merit de-energizing a powerful electrical transmission line that is now ...
In 2021, a survey conducted in the US polled 1500 adults, asking whether they believed that the US government was using the COVID-19 vaccine to place microchips in the American population. 5% of the survey takers said that this was definitely true and 15% said that it was probably true. [6]
