The voltage division rule can be used solve simple circuits or to simplify solving complicated circuits.

Voltage division across series resistors. For example voltage division among four resistors. The voltage across r 1 for example was 10 volts when the battery supply was 45 volts. Hence this is called voltage divider circuit.

The voltage across a resistor is often called a voltage drop if you have a complicated circuit that involves resistors in series and resistors in parallel pick two nearby resistors. The voltage across each resistor connected in series follows different rules to that of the series current. Find the total resistance across them using the rules for resistors in parallel or in series as appropriate.

It then uses the voltage divider formula of voltage drop across resistor 1 voltage inputresistance value of resistor 1total resistance in series where resistor 1 is the resistance of the individual resistor for which we want to find the voltage drop across. Voltage divider rule is that rule if a series circuit has more than one resistor. The rule can be easily extended to circuits with more than two resistors.

The proportionality of voltage drops ratio of one to another is strictly a function of resistance values. A simple example of a voltage divider is two resistors connected in series with the input voltage applied across the resistor pair and the output voltage emerging from the connection between them. Voltage division the circuit shows the principle of a voltage divider circuit where the output voltage drops across each resistor within the series chain with resistors r1 r2 r3 and r4 being referenced to some common reference point usually zero volts.

Which shows that the voltage is divided between two series resistors in direct proportion to their resistance. The voltage across of each resistor is the ratio of resistor value multiplied with voltage source to total resistance value. Thus here voltage is divided in the circuit across the resistors.

We know from the above circuit that the total supply voltage across the resistors is equal to the sum of the potential differences across r 1 r 2 and r 3 v ab v r1 v r2 v r3 9v. A voltage divider includes a voltage source across a series of two resistors. But these different circuits should always be the same.

Voltage division is the result of distributing the input voltage among the components of the divider. Thus in the given circuit the values of the voltage across each resistor are therefore voltage across r1 is 4v and voltage across r2 is 8v. With a little more observation it becomes apparent that the voltage drop across each resistor is also a fixed proportion of the supply voltage.
