Answer: For electricity to flow in a simple circuit, all of the following are required except an open loop.
Step-by-step explanation:
An open loop will resist the flow of electric current in a circuit due to which the current is not supplied completely into the circuit.
As a result, electricity will not flow in a simple circuit when there is an open loop.
Resistance, current, a closed loop and voltage are responsible for providing electricity in a simple circuit.
Thus, we can conclude that for electricity to flow in a simple circuit, all of the following are required except an open loop.
