Potential difference- Charge flows when there is a potential difference or a difference in potential.
Elective current- simply the flow of electric charge.
Amperes- Measurement of electric current.
Voltage Source- something that provides a Potential difference.
Electric Resistance- the current also depends on the resistance that the conductor offers to flow charge.
Ohms-electric resistance is measured in units called Ohms.
Ohm's law-this relationship among voltage, current, and resistance is called ohm's law
Direct Current-refers to a flow of charge that always flows in one direction.
Alternating Current- electrons in the circuit move first in one direction and then in the opposite direction.
Diode- A tiny electronic device that acts as a one way value to allow electron flow in only one direction.
Electric power-the rate at which electrical energy is converted into another form such as mechanical energy, heat, or light.
