Answer #1

Answer is C

a).Ashort to ground causes decreased current flow - False. A short to ground causes increased current flow.

b).An open causes unwanted voltage drop - False. An open does not causes any unwanted voltage drop.

c).High resistance problems can cause damage to wiring and connections - True. if the resistance is too high or too low,it can cause damage to wiring and connections due to excessive heat around joints or connection.For a circuit of high current flowing even if there exists unwanted small resistance it will create high amount of heat around that resistor which can damage the connections.

d). High resistance problems may cause damage to wiring and connections -False. This is same as that of 3 but this sentence is a prediction. Since we explained 3 we can treat answer as false.

In lab, we connect the power and ground through two approximately 24-inch 22-gauge copper wires. The total resistance of this 48 inches of wire is about 63mΩ. The total inductance is about 2:0 H. Perform the following two calculations and think about the implications of the result. Consider a circuit that is initially drawing 0mA and then linearly ramps up to a final current of 10mA in 2.5 nanoseconds. (This might be a typical value for a 40MHz clock signal...
