9.3 Determine the current ig through the resistor of Fig. 9.7 for t> 0 if iL(0-) = 6 A and ve (0+) = 0 V. The configuration of the circuit prior to t=0 is not known.

II- Research how engineers dispose of the waste produced by the generation of nuclear energy. Be specific and provide details. Please cite sources for all research completed while answering this question. Explain in detail regulations and environmental concerns that may apply (include a minimum of three – more is better). Be specific and provide details. Please cite all your sources. Which field(s) of engineering is involved with these disposal Projects? Are these fields of engineering of interest to you? Why or why not. Explain in detail    Answer all 3

The contractor is controlled by?

Assuming all terminals are rated 75°C and you have a  #10 AWG THHN/THWN conductors in a conduit and the conduit is run on the roof off a office building where the ambient temperature never rises above 30°C the largest size circuit breaker or fuse permitted to protect these wires is:?

The wording that I am running into with questions such as "The number of conductors required to be installed between three-way and four-way switches is " is confusing.  The text is not expalining this in a way that I am understanding anything other than grounding conductor, which is optional unless I am using a metal box.  So what type of "conductor" is beng discussed?
