Question

When Rhonda turns on the microcurrent device, the power results from a(n) _____, which is a path of negative and positive electric currents moving from the generating source, through the conductors, and back.

a) Open circuit
b) Short circuit
c) Electric field
d) Closed circuit

Answer 1

A closed circuit is the path of negative and positive electric currents moving from the generating source, through the conductors, and back. When Rhonda turns on the microcurrent device, the power results from a closed circuit.

Step-by-step explanation:

A closed circuit is the path of negative and positive electric currents moving from the generating source, through the conductors, and back. When Rhonda turns on the microcurrent device, the power results from a closed circuit. In a closed circuit, the electric current flows continuously and the electric device, like the microcurrent device in this case, can operate properly.

For example, if we think about a simple circuit with a battery, wires, and a light bulb, when the circuit is closed (meaning all the parts are connected in a loop), the electric current can flow from the battery, through the wires, and into the light bulb, causing it to light up. However, if the circuit is open (meaning there is a break in the loop, such as if a wire is disconnected), the electric current cannot flow, and the light bulb will not light up.
