Topic 3:Electric circuits Flashcards
Define current
The rate of flow of charge
Define voltage
The amount of energy a component transfers per unit of charge
Define charge
The fundamental property of a particle
Define EMF
Electromotive force
When energy transfers from another form of energy to electrical energy.
Define potential difference
The Difference between the amount of energy a charge carries between two points
Define Resistance
The measure of how difficult it is for a current to flow through a component
Define Resistivity
Define Drift velocity
The Average net velocity that electrons move with when in an electric field.
Define Electrical Power
The rate at which work is done/energy is transferred
Define Efficiency
The percentage of a total input that is useful for completing a task.
Define Series circuit
when components in a circuit are on the same branch.
Define Parallel circuit
When the components in a circuit are on separate branches parallel to each other
Define Electronvolt
The amount of energy an electron will gain when it moves from one volt.
Define Semiconductor
Materials that can conduct electrons under certain conditions Due to the small gap between the conduction & valance bands
Define valence bonds
The last electron shell with electrons(outer shell electrons)
