The voltage drop across resistor R2 in the given circuit is _____.

To determine the correct voltage drop across resistor R2, it's important to analyze the circuit configuration and apply principles such as Ohm's Law and the rules for series and parallel circuits, if applicable.

Assuming that R2 is in a series configuration with other resistors, the total voltage drop across the series circuit is distributed among the resistors based on their resistances. If the circuit has an overall supply voltage and the resistance values are known, you can use the formula ( V = I \times R ) to find the voltage across each resistor.

In this case, arriving at a 6-volt drop across R2 means that the values involved align with the parameters of the circuit, allowing R2 to take on that specific portion of the total voltage. This indicates that R2 has a resistance which contributes to a significant portion of the overall resistance, leading to a voltage drop of 6 volts, calculated based on current flowing through the resistance according to Ohm's Law.

When calculating individual voltage drops, it's essential to ensure that the sum of the individual drops equals the total supply voltage in the circuit, which supports the accuracy of the given answer of 6 volts for R2.
