Electric circuit
systems where electric charge flow through a close loops
Electric current (I)
the rate in which electric flow through a conductor
Direct current (DC)
current that carrier flow in a single direction
Electric potential difference (V)
energy per unit charge to move a positive charge between 2 points
Power dissipated
rate in which energy is transferred
Resistance (R)
a measure how much material oppose the flow of electric current
Resistivity
a material property that quantify how strongly it resist the flow of electric current
Ohm Law
stated that current through a conductor is directly proportional to the potential difference
Ohmic material
material that obey the Ohm law, will have a constant resistance
Variable resistor
components that allow you to adjust the resistance in a circuit.
Internal Resistance (r)
resistance within the battery that are caused by the materials and the chemical reaction inside it
Electromotive force (emf)
work done per unit charge to move a charge around a circuit
