Answer to Question 1

ANS: A
Electrical currents are influenced by voltage (the electromotive force pushing electrons forward) and the resistance electrons must overcome along the conductive pathway. An insulator is the material surrounding the conductive material and is usually made of plastic.

Answer to Question 2

ANS: A
According to Kirchhoff's laws regarding series circuits, total resistance is equal to the sum of all resistors in the circuit. If the circuit has three resistors, total resistance = A + B + C. Therefore, 100 = A + B + C. If one resistor is 40 , then 100 = 40 + B + C and the sum of B + C must equal 60 .
