19
Q

In order for electricity to be useful, we need a steady flow of it, known as a…?

A

current

20
Q

In a battery, the electrons form from where?

A

The negative terminal of the battery

21
Q

The path for electrons to move through must be a…?

A

Conductor

22
Q

What is a conductor?

A

a material that allows electrons to move through it easily

23
Q

Most metals are good or bad conductors?

A

good

24

What is an insulator?

A

a material that electrons have a hard time moving through

25
Q

An example of an insulator is…?

26
Q

What is the load?

A

The object that uses electricity for power?

27
Q

What is the load in the circuits you’ve been making?

A

the light bulb

28
Q

The switch controls…?

A

the flow of electrons by opening and closing the circuit

29
Q

A direct current uses what kind of power source?

A

battery

30
Q

What is a closed circuit?

A

It is when there is a complete path for current to flow

31
Q

What is an open circuit

A

When a circuit does NOT have a complete path for current to flow. It is therefore not functional.
