Electricity

If you have a series circuit with 4 bulbs and you unscrew the 2nd bulb what will happen to the rest of them?

• All the bulbs after the 2nd bulb will turn off

• The rest of the bulbs will turn off

• All the bulbs will get brighter
• The circuit will explode

in an open parallel circuit with 3 bulbs what will happen if the 3rd one is unscrewed?

• they aren't on in the first place

• the first two get brighter

• bulb 1 will stay lit

• bulb two will stay lit

what is wrong with a series circuit that has a bulb, open switch, and battery?

• the bulb

• the switch

• the battery

when a lightbulb is unscrewed from a series circuit, it does not affect the other bulbs.

• true

• false

formula for voltage

• V=IxR

• R=V/I

• I=V/R

• V=R/I

why is rubber wrapped around wires?

• to help the electrons flow smoother

• safety

• to make the current stronger

When the resistance increases the current increases

• True

• False

when resistance increases voltage

• increases

• descreases
