The equations (18, 19) can be used to find out the voltages in series connected resistors in terms of total voltage across the series combination and the values of individual resistors. These equations are called voltage division rule.
DIVISION OF VOLTAGE IN SERIES CIRCUIT
Figure
1.11 shows two resistors R1 and R2 in series and
connected to a DC source of V. I is the current flowing through the resistances
R1 and R2. V1 and V2 are the
voltage drop across R1 and R2 respectively. Here,
resistances are in series connection, so the same current I flows through them.

Generally,
Voltage across one of the resistors = Total voltage across series circuit × Value of the particular resistor / Sum of the individual resistors
