Current Divider Rule (CDR)
What is Current Divider Rule (CDR)? When a number of elements are connected in parallel, the current divides into a number of parallel paths. And the voltage is the same for all elements which are equal to the source voltage. In other words, when the current passes through more than one parallel path (the voltage divider rule "VDR" or voltage division is …
