8th grade Electricity

what is electricity?

• force created by a difference in charges due to gained or lost electrons

• sends a flow of electrons in 1 direction

• material which prevents the flow of electrons

what is an example of static electricity

• touching a charging phone

• touching a wire

• walking across your carpet in socks and then touvhing your cats nose

• walking acroos your carpet with socks and then touching your moms nose

which way does electricity move

• positive to negative

• up and down

• negative to positive

• side to side

Materials called resistors can fasten the flow of electricity

• true, it fastens it

• false, it slows

what will flow in only 1 direction ?

• insulators

• direct current

• alternating current

• series circuit

true or false: the difference in charges between 2 points is called the voltage.

• true

• false

what is an electric circuit?

• is one whish has only one pathway for electricity to flow

• materials which prevent the flow of electrons

• has multiple pathways which electricity can travel down

• a circuit is a pathway along which an electric current can travel, in route to device

a schematic diagram uses symbols to show electrical circuits and wiring

• true

• false

A parallel circuit has only one path which electricity can travel down.

• false

• true

what happens in a parallel circuit if one pathway is broken or open

• it will all shut down and wont work

• the other pathways can still carry electricity
