In a series circuit, the sum of the voltages dropped across all components is equal to what?

Explanation:
In a series circuit, voltages around the loop add up to the total voltage supplied by the source. This is Kirchhoff’s Voltage Law in action: the sum of the voltage drops across each component equals the source voltage since the same current flows through every element and energy is conserved around the loop. For example, if the source provides 12 V and the drops across components are 5 V and 7 V, those drops add to 12 V. Because the relationship is additive, the correct idea is that the voltages drop across all components sum to the supply voltage.
