Heating and Magnetic Effects of Electric Current: Concepts.

Electric current is the rate of the charge flow past a specified spot in an electric circuitand is measured in amperes. The atoms in a battery can have an absence of electrons, causing a positive charge. Reversing it, if the atoms have more electrons, then it carries a negative charge. A charge flows from one end to the other, and it only flows when there is a potential difference, which is a.

The hazards of electricity (see table below) depend on the amount of electrical current, its frequency, its duration, its path through the body, and the physical condition of the person. Alternating current at 60 Hz is slightly more dangerous than direct current, but high frequency currents (greater than a few kHz) are safer because they tend to flow on the surface of the skin and away from.
