Keisha analyzes this circuit diagram. which circuit component should keisha use to start or stop the current in the circuit? w x y zanswer a

Component ' W ' is the standard schematic symbol for a switch.

The short line between the two circles can be shown straight,
like it is now, when the switch is 'closed' and current can flow.

Or, it can also be drawn slightly tilted, so it's not touching one
of the circles.  In that case, the switch is 'open', no current can
flow through it, and the whole circuit is shut down.
