What happens to the total voltage in a series circuit as more components are added?

In a series circuit, when more components are added, the total voltage across the circuit increases. This increase occurs because the total voltage is the sum of the individual voltages across each component. Each component, like a resistor or a light bulb, uses a portion of the total voltage provided by the power source, such as a battery.

When additional components are connected in series, the total voltage that the power source must supply increases to accommodate the combined voltage drops across all components. For example, if you have one resistor that drops 2 volts and you add another that drops another 2 volts, the total voltage drop across both resistors will be 4 volts. Thus, as you add more components, the overall voltage required for the entire circuit will continue to increase to ensure that each component can operate effectively within its voltage range.

This principle is essential in understanding how series circuits function, as it reveals the relationship between voltage, current, and resistance within the circuit.
