Question

Keisha analyzes this circuit diagram.

A circuit diagram with two small circles close to each other labeled W. A circle with an X in it on the top labeled X. On the right are parallel lines in alternating length perpendicular to the line of the circuit labeled Y. On the bottom of the circuit is a zig zag line labeled Z.
Which circuit component should Keisha use to start or stop the current in the circuit?

W
X
Y
Z

Answer 1

To start or stop the current in a circuit, Keisha should use a switch. In circuit diagrams, switches are often represented by specific symbols. Based on your description, if we assume "W" refers to two separate points close together that might represent a switch, then she should use "W."

If the labels correspond to standard components:

- "X" could represent a battery or power source.
- "Y" could represent resistors or other components, possibly capacitors depending on the representation.
- "Z" usually denotes a connection or wire, sometimes representing ground.

However, without seeing the actual symbols, the best assumption according to your description is that Keisha should use **W** to start or stop the current.
