Identify the true statements about testing parallel circuits. Question 14 options: a) In parallel circuits, you must always test each branch separately. b) Checking a schematic will tell you each branch circuit's voltage, so you can test that against voltage you measure in the loop circuit. c) If you test a parallel circuit with the switch closed, you'll get a reading that indicates continuity even if multiple branches within the circuit are open. d) If one circuit of a parallel circuit is open, power can't flow back to the source
