Q1. Which of the following is the least expensive protection for over current in low voltage system?

Q2. Fuel cell for power generation have drawback of.

Q3. In order that the voltage drops are equal in all the conductors, generally the position of the conductors is interchanged at regular intervals along the line such that each conductor occupies the original position of every other conductor over an equal distance. This exchange of conductor positions is called
