Simple Series and Parallel CircuitsUnderstanding how resistors behave in circuits is crucial for effective design.1. **Series Circuit Example**: In a series circuit, resistors are connected end-to-end. The total resistance is the sum of the individual resistances. For example, if you have two resistors, R1 (100Ω) and R2 (200Ω), the total resistance (R_total) is:\[ R_{total} = R_1 + R_2 = 100Ω + 200Ω = 300Ω \]2. **Parallel Circuit Example**: In a parallel circuit, resistors are connected across the same voltage source. The total resistance can be calculated using the formula:\[ \frac{1}{R_{total}} = \frac{1}{R_1} + \frac{1}{R_2} \]For example, if R1 is 100Ω and R2 is 200Ω, the total resistance is:\[ \frac{1}{R_{total}} = \frac{1}{100} + \frac{1}{200} = \frac{2 + 1}{200} = \frac{3}{200} \]Thus, \( R_{total} = \frac{200}{3} ≈ 66.67Ω \). B.
