11 combination circuit

  1. 1. Series Circuits Parallel Circuits The current is the same in every resistor; this current is equal to that in the battery. The voltage drop is the same across each parallel branch. The sum of the voltage drops across the individual resistors is equal to the voltage rating of the battery. The sum of the current in each individual branch is equal to the current outside the branches. The overall resistance of the collection of resistors is equal to the sum of the individual resistance values, Rtot = R1 + R2 + R3 + ... The equivalent or overall resistance of the collection of resistors is given by the equation1/Req = 1/R1 + 1/R2 + 1/R3 ...
