• Voltage is what pushes an electrical charge or
electrons) through a circuit. Also known as electrical
potential.
• Not to be confused with the electrical charge itself.
• Voltage is measured in volts.
• Remember when we learned about the electric
chair?
• Current is a flow of electric charge (the electrons) that are
being moved through an electrical circuit.
• Voltage is the force that moves current, and that is the
difference between the two concepts that are always
confused.
• Current is measured in Amperes.
• Is a quality of the opposition of current flow through an
electrical conductor measured in OHMS.
• An example of an electrical conductor can be
• In other words resistance is a ratio between voltage and
current which shows the quantity of current is being held back
in a circuit.
• Materials called super conductors do not have any resistance.
• An electrical circuit in which the electrical loads (example: a
lightbulb) are connected to a voltage source, along the same
conduction path.
• Expressed by the equation Vs = V1 + V2 ….
• An electrical circuit in which the electrical loads (example: a
lightbulb) are connected to a voltage source (example a
battery) parallel to the voltage source with their own
conduction path.
• Expressed by the equation Vs = V1 = V2 ….
• Know these for drawing an electrical circuit …..
