Term

Definition
flow of electrons through a conductor 


Term

Definition
electrons made to flow in one direction along the conductor the graph of waveform is a straight line 


Term

Definition
current in which electrons oscillate back and forth most applications require it waveform will be a sine curve electrons flow first in positive direction, then a negative direction once the reach maximum flow, the electric potential is reduced, returns to zero, and reverses the motion 


Term

Definition
a circuit in which the current only has one path to travel all component parts are connected end to end a break anywhere in the path results in an open circuit and stops flow of electrons the total resistance is equal to the sum of the individual resistances along the path sum of voltages across each resistor is equal to the total circuit voltage 


Term

Definition
a circuit in which there are more than one path for the current to flow components are branches of the main circuit a break in any one path doesnt interrupt the flow of charge in the other parts 


Term
resistance (series circuit) 

Definition
total resistance is equal to the sum of the seperate resistances Rt= R1+ R2+ R3 


Term

Definition
current is the same everywhere in the current It=I1=I2=I3 


Term
voltage drop (IR drop) series circuit 

Definition
sum of the voltage drops must add up to the EMF or voltage of the source Vt= V1+ V2+ V3 


Term

Definition
the total voltage is equal to the sum of all the voltages across each resistor 


Term

Definition
total power is the sum of the power consumed or dissipated by each resistor or load PT= P1+ P2+ P3 


Term
resistance (parallel circuit) 

Definition
the total resistance is always less than the lowest valued resistor 1/RT= 1/R1+ 1/R2+ 1/R3 


Term
current (parallel circuit) 

Definition
the total current will equal the sum of the current in each branch It= I1+ I2 +I3 


Term
voltage (parallel circuit) 

Definition
the same in all branches of the circuit Vt= V1= V2= V3 


Term

Definition
total power is the sum of all the power consumed in each branch Pt= P1+ P2+ P3
