Let your Burbank electrician teach you the absolute basics of the electrical circuit, including essential terms and diagrams for easy understanding. Learn what a switch is, what voltage is and how it affects current!

1. A Crash Course from B.K. Electric Services

2. ◦ Resistor: a electrical component or part that
creates a resistance to electricity.
◦ Fuse: a type of low-resistance resistor
◦ Load: a component that uses electricity, such as a
microwave, razor, light bulb, etc.
◦ Switch: an electrical part that can break a circuit
or interrupt/divert current.

3.  Voltage (V): simply the difference in potential
energy from the where the charge beings to
where it end. Think of it as pressure pushing
electrons around.
 Current (I): the flow of electrons through a
circuit per second, measured in amperes (A).
 Ohm (Ω): the amount of resistance, equal to
one volt creating one ampere or V/A.

4.  An electrical circuit is the path a group of
electrons will travel from point A to B.
 These electrons want to go from the negative
to psotive terminal in a loop. They are pushed
by voltage.

5.  These moving electrons carry energy that can
power a load (i.e. a light bulb). They will pass
through the load, then continue on to the
positive terminal of the battery.

6.  Switches are used to break circuits or interrupt or divert current. In the “On”
position, a conducting material drops to close the gap and complete the
circuit.
 In the “Off” position, that material lifts and creates a gap.

7.  The basic parts of a circuit are:
◦ a power source
◦ a conducting material
◦ a load
