Formula and explanation
The total voltage equals the sum of the voltages across each component: U(total) = U₁ + U₂ + + U n. Conditions: Series circuit (including sources, resistors, etc.). Explanation: This is a direct consequence of Kirchhoff's Voltage Law (KVL) for a series loop. The algebraic sum of potential differences around any closed loop is zero.
