In a series circuit the output of one element provide the input for the next element. When we want know the total resistance of a series circuit, we have to do this operation: R= R1+R2+R3.
Other example can be a series of generators that the sum of all the resitance values is the total resistance: V= V1+V2+V3.
PARALLEL CIRCUIT.
In a parallel circuit the output element share the same tan the input element. The potential difference is the same for eah element,but the current in each branch is different:
1/R= 1/R1+ 1/R2 + 1/R3....
If two equal batteries are connected in parallel, the voltage will not increase, but the total consumption of energy will be shared between the batteries.
COMBINATION CIRCUIT.
These type of electric circuit has elements connected in series and other elements connected in parallel. The current remains constant between elements that are connected in series and the voltage remains the same between elemens that are connected in parallel. For analyse their , first we calculate the current from each power source .
