Formula and explanation
The voltage U i across resistor R i is related to the total voltage U by: U i = (R i)/(R₁ + R₂ + + R n) U. Conditions: Pure resistive series circuit. Explanation: In a series circuit, the voltage divides in proportion to the resistance. A larger resistance gets a larger share of the voltage.
