Components of an electric circuit include the hot and the neutral parts. Usually, the hot part is referred to as the live wire in alternating circuits. When one touches the hot wire, through which current flows at varying potential difference, the individual risks suffering from shock hazard. On the other hand, when one touches the neutral part, then the individual can or cannot suffer from shock hazard depending on whether the circuit is grounded or not. When the circuit is grounded, neutral wire can be safe for touch. However, this is also risky because of unpredictable accidents, which involves electric leakages. Electric current flows through a complete circuit, if there is a potential difference across the circuit. Therefore, when one touches the circuit, the individual offers opposition to flow of current. Essentially, an individual that touches a complete circuit at the hot wire opposes the flow of electrons. From current electricity, it is known that opposing the flow of electrons results in dissipation of energy. Energy, which is dissipated usually, comes off in form of heat. Therefore, current heats the body and can burn essential body organs. Consequently, if the amount of heat given off is adequate then significant body tissues can burn. Additionally, electric current can affect the nervous system, which process several functions through the spinal cord, motor organs and the brain, among others.
