• Series and Indirect Contact

• Indirect and Open Contact

Which of the following factors influence the intensity of an electric shock?

• Voltage, wire material, and wire length

• Type of electrical device and distance from the source

• Current level, duration of exposure, and body pathway

• Frequency of electrical use and wire insulation type

What is one of the most common causes of indirect electric shock?

• Touching an insulated wire
