Term

Definition
 A flow of electric charge carriers 


Term
The Charge in terms of current flowing and time elapsed 

Definition


Term
Formula for the power in terms of the voltage and current 

Definition


Term
The formula for resistance in terms of the properties of the resistive wire 

Definition
[image] p = the resistivity of the wire l = length of wire A = crosssection area 


Term

Definition
At a constant temperature, the current in the conductor is proportional to the potential difference across the conductor  Note: V = IR is not actually a statement of Ohm's law although it derives from the law 


Term
Formula for Current in terms of A, n, v, q and what does each symbol mean 

Definition
I = Anvq A = cross section area n = number of electrons v = drift velocity of electron q = charge of electron (elementary charge) 


Term
Define potential difference 

Definition
The amount of energy per unit charge (coulomb) that is converted to other forms of energy when the current passes through a component
