Q

Is voltage the small across each light in series.

A

Yes, they should share the same amount of volts as the battery

17
Q

What is a insulator

A

Materials that do not allow electricity to pass through them

18
Q

Voltage in a seires

A

Total of battery gets divided equally between each light

19
Q

Voltage parallel

A

Not shared by each light

20
Q

current series

A

the same everywhere

21
Q

current parallel

A

It is divided by the #of branches

22
Q

How does voltage differ from current?

A

Voltage- if the amount of electrify going through the circuit
current- Is how fast the electrons are going.

23
Q

In order for a light to turn on the circuit must

A

Be closed

24
Q

Two light bulbs are connected in parallel circuit. If the first light is unscrewed what will happen to the second light bulb?

A

The brightness would remain the same.
