According to Kirchoff's Voltage Law, what does the sum of voltage drops across all resistors equal?

According to Kirchhoff's Voltage Law, the sum of all voltage drops in a closed circuit must equal the total voltage supplied by the sources in that circuit. This means that when you calculate the voltage across each resistor and add them up, the result will be equal to the voltage provided by the power source, such as a battery or power supply.

This law is based on the principle of conservation of energy, indicating that the energy supplied by the voltage source is used up across the components in the circuit. By understanding this, one can effectively analyze and design electrical circuits, ensuring that the voltage distributions are consistent with the energy supplied from the sources.

The other options do not reflect this relationship: the current through the resistors relates to the flow of electric charge and does not equate to voltage; resistance alone quantifies how much a component opposes current, without direct relation to voltage drops; and power consumption relates to how quickly energy is used but does not directly correspond to the sum of voltage drops.
