Electricity
a flow of electrons is called this
electric current
an example of a series circuit
Christmas lights from 1980's
an example of a parallel circuit
Exit lights for emergencies
Wood (conductor or insulator)
Insulator
a circle with an x through it
light
The path electricity follows
Circuit
if one christmas light is removed from the strand what happens
all turn off
if one single light turns off what happens to the rest
nothing
Copper.
Conductor
A zig zag line
Resistor
Give 3 uses for electrical circuits
Lighting, heating, appliances,
How does current flow in a series circuit?
How does current flow in a parallel circuit?
in one direction along multiple paths back to the battery
Water
conductor
a thin line and a thick line parallel attached to a wire signify this.
battery
item used to resist flow of current
resistor
What are two disadvantage with series circuit?
one light out, then will not work
needs bigger battery to power the circuit
What is an advantage of parallel circuits?
Requires less electricity
Will continue to work even if 1 light goes out
Multiple paths back to battery
Glass
Insulator
Two circles with a lever open signify this.
open switch
if there is no resistor, what happens to the LED
it might explode/burn out
Draw three lights in a series circuit with battery and wires.
Answers will vary.
Draw a circuit for 2 lights , a battery, and wire running in a parallel circuit.
Answers will vary.
Why are wires coated in rubber?
It's an insulator, it keeps the electricity inside the wire (and keeps us safe)
two circles with a closed line between them signify this.
closed circuit.
