```Electricity Within a Circuit
An electric circuit is a continuous pathway for
charges to move.
Circuit Elements and Diagrams
Circuits have 4 basic components:
1) Source – source of electric energy
(where the electricity is coming from)
(battery)
2)
Conductor – the wire through which
the energy flows (wire)
3)
Control – a switch or device that can
turn the circuit on or off. (switch)
4)
Load – items along the circuit that
convert electricity into other forms of
energy (examples: light bulbs, motors,
heaters, speakers).

Current
Electric current:
- is the amount of charge that passes a point
in a conducting wire every second.
- is measured in amperes (A) by an ammeter.
(weaker electric currents are measured by a
galvanometer).
- within in a circuit, negative charges
(electrons) flow on a path from the negative
terminal of a battery to the positive terminal
of the battery.
- is similar to a rivers current. A strong river
current means that water flows rapidly; a
fast flow rate.
Voltage
- is the energy of each individual charge.
- The symbol is V and the units are volts (V)
- Voltage is the push that makes electrons
move.
