Electrical Theory- Questions & Answers
Which of the following is true regarding a series circuit? Correct Ans-The current flow is the
same through all resistors.
Which of the following is true regarding a parallel circuit? Correct Ans-It has more than one
path for current to flow.
Which of the following is true regarding a series-parallel circuit? Correct Ans-If a circuit is
reduced to an equivalent series circuit, the total resistance is found by adding the loads.
