Download Load or device Battery or energy source

A CLOSED PATH MADE OF 3 PARTS…..
1 ENERGY SOURCE (battery or solar cell)
2 CONDUTOR (mostly metals, but water is also a great conductor)
3 LOAD
THROUGH WHICH ELECTRICAL CURRENT CAN FLOW
ADDED VOCABULARY….
BATTERY CHANGES CHEMICAL ENERGY INTO ELECTRICAL ENERGY
SOLAR CELL CHANGES SOLAR ENERGY INTO ELECTRICAL ENERGY
INSULATOR Covers a conductor (glass, plastic, rubber)
LOAD Device that uses electrical energy to operate. The load converts electrical energy
Into other forms of energy (electricity to light and heat) (cell phone electrical energy
into electromagnetic) (doorbell electricity to sound waves)

A line is pretty simple, it looks like a wire.
The load is the device using the electricity see how it looks like
Lightening on a wire. SO THIS IS WIRE DEVICE WIRE
Like on a battery which has a positive end (the one that sticks
out, hence bigger line) and the negative (the flat side, hence
the short side). SO THIS IS WIRE BATTERY WIRE
It is the opposite of what you think, open switches DO NOT
work because the current IS UNABLE TO flow to the load.
SO THIS IS WIRE SWITCH THAT IS OPEN WIRE
It is the opposite of what you think, closed switches work
because the current can flow to the load. SO THIS IS WIRE,
SWITCH THAT IS CLOSED, WIRE
9 In an open circuit the
wire goes to the switch,
but the switch is open so
the energy never crosses
over the switch to
continue down the wire
to the load or device

energy source
Load or device
NOTE:
1 energy source
More then one load
Series: if one load is
broken or disconnected
the circuit is open and
entire device cannot
work. (old fashioned
house lights for
holidays) Adding more
loads to the circuit
shares the energy
source and less energy
goes to each load.
NOTE:
1 energy source
More then one load

Paralle: if one load is
broken in one wire or
disconnected the circuit
is still closed and entire
device (other than the
disconnected or broken
part) works (the house
lights for holidays used
today). Adding more
loads does not alter the
voltage going to each
load because each load
has the same voltage.
Single wire or path for
Electric current
Same current for all loads
Or devices
Open circuit (break,
Disconnect) makes
All loads or devices
unable
To work
Multiple wires or path for
Electric current
Current can vary among the
Different wires or paths
(break,
Disconnect) does not open the
Entire circuit since there are multiple
Paths so only part of the load does not work
Safety caps so baby fingers
cannot go in the
Open circuits are incomplete circuits and cannot
operate a device. Closed circuits are complete
and the device functions
In a series all devices are connected by 1 wire so
Removing 1 bulb or load makes the entire circuit
Open and all lights go out.
Every time one device was used all of
the devices including the one device
in use would not get energy so none
of the devices would work.
