Brief Description
Explanation of how to solve basic circuits problems.


Series Circuits

  • The current is the same in every resistor; this current is equal to that in the battery.
  • The sum of the voltage drops across the individual resistors is equal to the voltage rating of the battery.
  • The overall resistance of the collection of resistors is equal to the sum of the individual resistance values,
Rtot = R1 + R2 + R3 + ...

Parallel Circuits
  • The voltage drop is the same across each parallel branch.
  • The sum of the current in each individual branch is equal to the current outside the branches.
  • The equivalent or overall resistance of the collection of resistors is given by the equation
    1/Req = 1/R1 + 1/R2 + 1/R3 ...
