Answer

a. Electrical current - The rate at which of electrons flow through a conductor, such as a copper wire. Electrical current is often compared to water flowing in a pipe. Current is measured in Amperes, abbreviated as (A) b. Voltage - The energy potential between two points in an electric circuit. Voltage is measured in volts, abbreviated as (V) c. An open switch - Stops current from flowing through the circuit, by moving relevant conductors such that they do making contact. d. A closed switch - Allows current to flow through the circuit by created a closed path of conductors in the circuit. e. Direct current - Current which is constant over time, abbreviated as DC. f. Alternating Current - Current which periodically alternates direction with time, abbreviated as AC.
