Question

Exercise 2.1 :Find the equivalent resistance for each of the networks shown in Figure 2.4 [Hint for part (b): R, and R, are in parallel.]

Answer 1

To determine the equivalent resistance of a mixed resistor network, calculate the resistance of parallel resistors first, then add the result to the series resistance.

Step-by-step explanation:

Finding Equivalent Resistance

To find the equivalent resistance of the circuit described, you need to understand the difference between resistors in series and parallel. Resistors in series are simply added together. For resistors in parallel, the equivalent resistance (Rp) can be found using the formula 1/Rp = (1/R2) + (1/R3), where R2 and R3 are the resistances of the individual resistors.

Once you have found the equivalent resistance of the parallel network, add it to the resistance in series (R1) to find the total equivalent resistance (Rtot) of the circuit. The formula for this is Rtot = R1 + Rp. Insert the known values into the equation to calculate the total equivalent resistance.
