Electric Circuit
Electric Circuit is a closed path that electric current follows.
Electric current is a flow of electric charges.
What kind of charges
flow?
Series circuit
A series circuit has only one path for its current to follow.
An example of a series circuit would be Christmas tree lights. The lights will go out if a bulb is removed.
What happens if I remove a light from a series circuit?
Parallel Circuits Parallel Circuits has
more than one path for the current to follow.
A parallel circuit allows for many devices to be turned on and off at different times.
Where do we use a parallel circuit?
What would happen if I took out a light bulb?
Resistance
Resistance is how much a material
opposes the flow of current.
Thin wire has a greater resistance than
thick wire.
Short circuit
A short circuit is where current flows
where it isn’t wanted.
What would happen if the plastic around a
plug came off?
1. What kind of charges flow
through a circuit?
3. What kind of circuit is pictured
below?
2. Which kind of circuit would be
best to use in a home?A. Series circuit
B. Parallel circuit
4. What kind of circuit do we see
most often with Christmas tree
lights?
A. Series Circuit
B. Parallel Circuit
5. Please draw a series circuit if you
were given a battery, light bulb, and
wires.
