The Voltage Divider Rule is used to calculate the voltage drop across individual resistors connected in series.
In a series circuit, the same current flows through all resistors, while the supply voltage is divided among them according to their resistance values. A resistor with a higher resistance has a greater voltage drop.
Formula:
V₁ = Vₛ × R₁ / (R₁ + R₂)
V₂ = Vₛ × R₂ / (R₁ + R₂)
Where:
- Vₛ = Supply voltage
- V₁, V₂ = Voltage drops across resistors
- R₁, R₂ = Resistance values
Total Voltage:
Vₛ = V₁ + V₂
