Question
(10%) Problem 9: Conductors permit the flow of electric current, while insulators block such flow. That simple concept becomes more difficult when multiple layers of material are involved. For a continuous path through such a compound material to be electrically conductive, the path must contain only conductors Part A Plastic Plastic FR-4 Part B ©theexpertta.com 50% Part (a) In part A a piece of copper is sandwiched between two pieces of plastic. This is a simple model of electrical wiring. Check all answers that apply Grade Summary Deductions Potential The path from point A to point D is electrically conductive The path from point A to point C is electrically conductive The path from point B to point D is electrically conductive The path from point A to point D is electrically conductive 0% 100% Submissions Attempts remaining: 5 I give up! % per attempt) detailed view Submit Hints: 0 for a 0% deduction. Hints remaining: 0 Feedback: 2% deduction per feedback. 50% Part (b) All modern electronics contain printed-circuit boards to hold electrical components and make electrical connections. Many printed circuit boards are made of an insulator called FR-4. Although copper is used for the conductive traces, contact points are occasionally coated in gold for its corrosion resistance. For the sandwiched materials shown in Part B of the figure, select all the correct statementsExplanation / Answer
since plastic is insulator and copper is conductor
then part A is model of electrical wiring
so the answer is The path from point B to point D is electrically conductive
