The value of current passes through a particular branch depends on the impedance of that branch. V s = i s r 1 + i s r 2 = i s ( r 1 + r 2) i s = v s r 1.

The voltage divider rule formula (vdr) shows how the voltage distributes among different resistors in a series circuit. Vr = (r/r t) × vt this formula can be used for any number of series resistances because of the direct proportion between

Voltage division rule is one of the basic rules of circuit analysis. The formula for current division rule may be written as below.

Example Of Voltage Divider Rule:

Series circuit always acts as a voltage divider. The kvl equation around the loop will be. One of the common mistakes in using the voltage division rule is to use the formula for resistors which are in parallel with other elements.

We Can Write This Rule In Words As Given Below.

Now, according to current divider formula the current through resistor r 1 is given by (11) current through resistor r 2 is given by (12) now, add equation (11) and (12) we get, so that according to kirchhoff’s current rule, all the branches current is equal to the total current. I 2 = 10 x 10/25 = 4a. According to the currentdivider rule, current in through any resistor = total current of the network x resistance of other resistor/equivalent resistance of the circuit.

Applying Formula, Voltage Across 100Ω Resistance V 1 = (100*6)/(200+100) = 2V

By selecting appropriate values of resistors in the divider, it is easy to obtain a fraction of the input voltage. Here is a simple but useful tip to calculate the voltage and current from resistor chains. Current divider rule “cdr” calculator;

The Voltage Division Rule Can Be Understood By Considering A Series Circuit Shown Below.

By substitution of vs/rtfor i in the expression for vx, vx=(vs/rt)rx. The formula for voltage division rule for “n” number of series connected resistance is given below. In other words, when the current passes through more than one parallel path (the voltage divider rule “vdr” or voltage division is used to calculate the voltage in the series circuits), the current divide in each path.

In The Circuit Of Figure, The Total Resistance Is R1+R2+R3+.

As we know, i = v/r or we can say i = e/r Where 8 ω is in parallel to the output voltage. Voltage divider rule for ac circuit:
