DC circuitsQuestion 701 of 1506

An electrician must analyze a circuit in which some resistors are in series and others are in parallel. How are the series and parallel rules used?

  1. The parallel rules are used for the whole circuit
  2. Each rule is applied only to the part of the circuit where it fits
  3. Neither set of rules can be used
  4. The series rules are used for the whole circuit
Show answer

Correct answer: Each rule is applied only to the part of the circuit where it fits

The circuit is broken into series and parallel parts and the matching rules are applied to each part.
