What type of circuit is illustrated? a. a closed series circuit b. an open series circuit c. an open parallel circuit d. a closed parallel circuit

An open series circuit is an electrical circuit in which the electric current does not circulate because the switch is open interrupting the flow of current. There must be a closed path for the current to flow through the circuit.
