Analyzing circuit behavior is crucial for designing effective electrical systems.

Description

Circuit Analysis

A circuit consists of three resistors in series (2Ω, 3Ω, and 5Ω) and another circuit with the same resistors in parallel. Compare the total resistance of both circuits.

  1. a

    State the total resistance of the series circuit.

    Aim for approximately 1 distinct marking point.

    [1]
  2. b

    State the total resistance of the parallel circuit.

    Aim for approximately 1 distinct marking point.
