Sum of Voltage Drops vs Source Voltage
Formula
## Kirchhoff's Voltage Law (KVL) The sum of all voltages around any closed loop equals zero. ### Principle **V_source = V_drop1 + V_drop2 + V_drop3 + ...** If drops do not sum to the source, there is an unaccounted component.
Exemplo Resolvido
12 V source with drops of 4 V, 5 V, and 3 V.
- 01Sum = 4 + 5 + 3 = 12 V
- 02Unaccounted = 12 - 12 = 0 V
- 03KVL is satisfied.
Perguntas Frequentes
What is KVL?
The algebraic sum of all voltages around any closed loop is zero.
What does a nonzero remainder mean?
An unaccounted voltage drop or measurement error exists in the loop.
Does KVL apply to AC circuits?
Yes, using phasor voltages.
