Answer to Question 1

Electrical current is produced by the flow of electrons. The unit of measurement for current is amperes (or amps). One amp is a current flow of 6.28 x 1018 electrons per second. Current is usually designed by I. Ohm's law describes the relationship among volts, ohms, and amps. One ohm is the resistance of a conductor that has a current of one amp under the potential of one volt.

Answer to Question 2

Electrical hazards occur when a person makes contact with a conductor carrying a current and simultaneously contacts the ground or another object that includes a conductive path to the ground. This person completes the circuit loop by providing a load for the circuit and thereby enables the current to pass through his or her body.
