What are the relation between individual voltage and the total voltage when resistors are connected in series?

Answer 1

when A resistance is connected across the supply voltage, total input vooltage will be drop in the resistance when the resistances are connected across the supply voltage, total input vooltage will be devidedacross the resistances. IF R value will be high ,drop also high. IF R value wll be low ,voltage drop will be less.

Answer 2

The total resistance of resistors in series is simply the sum of the individual resistances. If you had three resistors, 100 Ohms, 200 Ohms, and 300 Ohms in series the total resistance would be 600 Ohms. If you apply a voltage to this series circuit, the current will (by Ohm's law) be voltage divided by resistance, so if you applied 6 Volts, you would have 0.01 Amperes, or 10 milli-amperes. Kirchoff's current law says that the current in every point of a series circuit is the same, so the current through each resistor would also be 10 mA. Back calculate with Ohm's law, and you find that the voltage across the three resistors is 1 Volt (100 Ohms), 2 Volts (200 Ohms), and 3 Volts (300 Ohms). Kirchoff's voltage law says that the sum of the voltage drops in a series circuit is equal to the total voltage drop across that circuit. In this case, that is confirmed, as 1 + 2 + 3 does equal 6. In summary, the relation between individual voltages and the total voltage when resistors are connected in series is that the individual voltage is proportional to the total voltage by the ratio of the individual resistor divided by the sum of the resistors.
