 If a conveyor motor trips out, how do you diagnose it? 1 Answer The answer they want: You uncouple it and see if it spins freely unloaded. This only is valid for small, accessible motors, the real answer is you test the motor with a Baker analyzer and look for your standard motor defects: turn to turn shorts, open circuits, and ground faults.

 Q2: A pnp transistor with its base connected to a voltage source, the V source is connected to a +10V source. The emitter of the transistor is connected to a resistance, and then to the same +10V source. The collector side is connected to a capacitor, which is not charged at t=0-. Given the graph of Vsource = 10 V stepping up at t = 0 to further, draw the graph of Vout. Vout is between the point of collector and capacitor. 2 Answers ANS: Vout should be constantly -10V until t=0, and will hit V=0 V linearly from V=-10 V after t=0. Hi, Can you explain why it linearly increases? Are you assuming that Collector is tied to -10V? The pnp transistor is completely cutoff for the given biasing. The only way the capacitor is going to charge is through leakage currents. It is very slow and takes a lot of time. Please advise me if my analysis is correct.

 A boat is in a swimming pool and there is a rock in the boat. What happens to the level of water if the rock is thrown out of the boat? 5 Answers It depends on the density of the rock If the rock sinks: the water level actually falls....think about it...but this is the right answer. Stays the same (see ice melting in water physics problem; buoyancy) level of water increase Show More Responses Any rock that will have the density less than water?... It will fall because due to Achimedes' Law the total bouyant force decreased, hence so it is with the volume of space occupied below the water level. It depends on the ratio of volume of the rock vs the displacement of water. This is dependent on the density of the substance. In the boat it should displace a volume of water greater than the volume of the rock since the density of the rock is greater than the density of the water. Once in the water it should displace only it's own volume which do to it's density is less than the water it had to displace while in the boat.; hence, the water level decreases.

### Electrical Engineering Intern at Rockwell Automation was asked...

Oct 20, 2013
 What are some of your weaknesses? 3 Answers That sometimes I am too attentive to detail. I know this may be said alot, but it is true, I tend to pour over details to make sure there aren't any errors, which could sometimes consume too much time. was there a drug test? urine or hair? Employment offer is made pending urine drug test.

### Electrical Engineering Intern at TE Connectivity was asked...

Mar 4, 2012
 Arcing is bad for an electrical system, to deal with it we need to characterize it first. How would you measure the Electrical Characteristics of an Arc? 2 Answers - - - - - - - - - - -- - - - - -- - - - - - - - - -- - - Thats how I would do it. From what I know, the potential of the arc is directly proportional to the distance that it travels. I believe it's on the order of 1 inch per 1000 volts.
