Kirchoff's Voltage Law for a series circuit says that the total voltage is equal to __________.

Kirchoff's Voltage Law (KVL) states that the total voltage around a closed loop or circuit is equal to the sum of the voltage drops across each component within that loop. This law is based on the conservation of energy principle, which asserts that the energy supplied by the voltage sources in a circuit must be equal to the energy used by the components (like resistors, capacitors, etc.).

In a series circuit, the voltage supplied by the power source is divided among the various components, and the sum of these individual voltage drops must equal the total voltage provided by the power source. Therefore, if you were to measure the voltage across each component and then add those voltages together, the result would equal the total voltage from the source.

This accurately reflects how energy is conserved in electrical circuits, where the energy supplied is always used up by the components in the loop. Hence, the correct answer aligns perfectly with Kirchoff's Voltage Law.
