Sparkling — Switches & Circuit Paths Switch Tower

Hi!

I'm Sparkling.

Welcome to Switch Tower!

Will you help me investigate switches & circuit paths?

The Grumblies have mixed up our clues.

Let's check the evidence!

A switch opens or closes a circuit path.

A closed switch connects the path;

an open switch breaks it.

What does an open switch do?

  • A. Breaks the path
  • B. Completes every possible path
  • C. Creates energy from nothing

The answer is A: Breaks the path

A switch opens or closes a circuit path.

A closed switch connects the path;

an open switch breaks it.

That clue helps us make sense of this place.

In a simple single-path circuit, a break anywhere in

that path can stop the lamp operating.

Circuit symbols represent connections, not miniature photographs.

When does the lamp work in our model?

  • A. When A is open
  • B. When the source is removed
  • C. When A is closed

The answer is C: When A is closed

Our source and lamp are connected except for Switch A.

The lamp is off when A is open and on

when A closes in the supplied working model.

Hmm...

how does that connect to our first clue?

Our source and lamp are connected except for Switch A.

The lamp is off when A is open and on

when A closes in the supplied working model.

Can a break elsewhere also stop this single-path circuit?

  • A. Only if the gap is near the label
  • B. Yes
  • C. No

The answer is B: Yes

In a simple single-path circuit, a break anywhere in

that path can stop the lamp operating.

Circuit symbols represent connections, not miniature photographs.

Nice investigating!
