What happens to voltage in a series circuit with identical resistors?

• A. Voltage divides among the resistors
• B. Voltage doubles at each resistor
• C. The voltage remains constant
• D. Voltage is absorbed entirely by one resistor

Answer: (A)

In a series circuit with identical resistors, the voltage does indeed divide among the resistors. When multiple resistors of equal resistance are connected in series, the total voltage supplied by the power source is divided equally across each resistor.

For instance, if you have three identical resistors connected in series to a 12-volt battery, each resistor will have a voltage drop of 4 volts. This division occurs because, according to Ohm's law, the voltage across a resistor in a series circuit is proportional to its resistance; when all resistances are equal, the voltage is evenly split.

This characteristic of series circuits helps in understanding how voltage behaves under different conditions and is essential for applications requiring voltage regulation across multiple components. The other options do not accurately describe the behavior of voltage in this scenario.
