Four electricians are discussing wiring under raised floors in information technology equipment rooms. Electrician A says that wiring under the raised floor requires fire-resistant walls, floors, and ceilings between other occupancies. Electrician B says that wiring under the raised floor requires fire resistant halfway up the walls and floors between other occupancies. Electrician C says that the room must employ a disconnecting means that removes half of the power to all equipment in the room. Electrician D says that a disconnecting means isn't necessary for the room. Which of the following statements is correct? A. Electrician B is correct. B. Electrician D is correct. C. Electrician A is correct. D. Electrician C is correct.

The circuit diagram below is for a robot that walks around the room. It is designed to stop walking when certain conditions are met.   a) In which of the following cases will the robot start walking? i. The robot is far from the wall. ii. The battery status is good. iii. The room lights are on. iv. Both i and ii. v. i, ii, and iii. vi. ii and iii, but not i. vii. i and iii, but not ii.  b) Explain what happens to the robot if the light is turned off. ______________________________________________________________________________ ______________________________________________________________________________  c) If you remove the light sensor and the AND gate attached to it from the circuit from the circuit, which of the following are true and which are false? i. The robot will continue to walk with a low battery ii. The robot will stop walking if it is close to the wall iii. One of the remaining inputs (proximity sensor and battery status) is irrelevant to whether the robot walks or not.…
