When do electric appliances begin to flow electricity?

Electric appliances begin to flow electricity once they are turned on because this action completes the circuit and allows current to flow through the appliance to perform its intended function. When an appliance is off, the circuit is open, preventing any current from flowing, regardless of whether it is plugged in or not. The act of turning on the appliance signals the electrical system to allow power to travel through the circuit, powering the internal components necessary for operation.

While appliances can have certain functions like clock displays or standby modes that draw minimal power when off, these scenarios are not the primary operation of the appliance. Fluctuations in voltage can affect the functionality or performance of electrical systems but do not inherently equate to the initiation of power flow in the context of regular appliance operation. Therefore, the most direct and accurate response to when electric appliances begin to flow electricity is when they are actively turned on.
