## Voltage Division Rule ( Voltage Division In A Series Circuit )

why voltage division rule is used ?

For solving complex circuits and to simplify them we are using voltage division rule. Applying voltage division rule can also solve simple circuits thoroughly The main concept of this voltage divider rule is is “ The voltage is divided between two resistors which are connected in series in direct proportion to their resistance. circuit and the equation  are the two important parts of Voltage division rule.

### Voltage division Rule Derivation :

In series circuit, same current flows through each of the given resistance, Figure shows three resistors connected in series.

## Current Division Rule  ( Division Of Current In Parallel Circuit )

why current division rule is used ?

As we all know, in a parallel circuit current divides into all branches. The current flows by way of every branch is inversely proportional to the resistance supplied by every one them. The branch having higher resistance permits lesser current and the branch having lesser resistance permits extra current. Current division rule is utilized whereas finding current flows by way of every branch of the circuit.

A current divider is an easy linear circuit that produces an output current  that could be a fraction of its input current. Current division refers back to the splitting of current between the branches of the divider. The currents within the varied branches of such a circuit will all the time divide in such a manner as to minimize the total energy expended.

### Current Divider Rule Derivation

Consider two resistors connected in parallel as shown in figure. In parallel circuits, the voltages across all branches are equal.
