ABSTRACT

The average person is aware that electricity can be dangerous if not used or worked on properly, using safe work practices. Injuries resulting from electricity include electrocution, electrical shock, falls, and burns, which if left untreated can become infected. This chapter discusses the basics of electricity and the basic practices to prevent injuries related to it. To understand electricity, three important concepts must be mastered, which include voltage, current, and resistance. In a parallel circuit, the electrical current to each element in the circuit is separate; hence, if one element was to burn out, the other resistors would still have power. Resistors are elements of electrical and electronic systems that are designed to intentionally resist the flow of electrical current through the system at a known measurement. A capacitor or condenser is a passive electronic component consisting of a pair of conductors separated by a dielectric. Arc blasts occur when powerful, high-amperage currents arc through the air.
