CURRENT AND VOLTAGE DIVISSION

Current division:

This rule of current division is useful to find the current thought an individual branch impedance when there are more number of impedance's connected in PARALLEL.

For example:

Here if we want to measure the current I(1)  passing through Z(1) then,

                    I(1)=I×Z(2)/Z(1)+Z(2)

Similarly,   I(2)=I×Z(1)/Z(1)+Z(2)

Thus current through a particular individual branch impedance can be calculated using current division rule.

Voltage division rule:

This rule of voltage division is used to determine the voltage in a particular individual branch impedance when there are more number of impedance's connected in SERIES.

For example:

Here if we want to determine the voltage in any of the impedance's Z(1),Z(2),Z(3) ......Z (n)

We can use voltage division rule.

                  V(1)= V×Z(1)/Z(1)+Z(2)+Z(3)+....Z(n)

Similarly, V(2)=V×Z(2)/Z(1)+Z(2)+Z(3)+....Z(n)

                  V(3)= V×Z(3)/Z(1)+Z(2)+Z(3)+....Z(n)

And so we can calculate the voltage in any individual impedance accurately by using Voltage division rule.
