Question

A resistor with a resistance of 10 ohms is connected in series with another resistor of unknown resistance. When a voltage of 12 volts is applied across the combination, a current of 1.5 amperes flows through the circuit. What is the resistance of the unknown resistor?

Expert Solution

Step 1: Introduction and Given Data

When multiple resistors are connected in series, the total resistance (R_total) of the circuit is simply the sum of each individual resistance.

This relationship can be expressed as:

$R_{total} = R_{1} + R_{2} + \dots + R_{n}$

where $R_{1}, R_{2}, \dots, R_{n}$ are the resistances of the individual resistors.
