state icing icing conditions and the external environment parameter monitoring unit measures automatically calculates the time required to melt the ice, after the completion of melting ice in a sub-conductor, intelligent controller circuit breaker current transfer onto another root wire, the two sub-ice...
Why is the electric field inside a conductor zero? Why are good conductors of heat also good conductors of electricity? What is the function of fuses or circuit breakers in a circuit? Why do we take a positive charge as a test charge?

A low voltage distribution system comprises a two-conductor track of which one conductor is an outer conductor formed by its casing and the other conductor is an inner copper strip held by insulation. An adaptor can be fitted anywhere along the track and interlocked by closing pivoted members so...
Explain why, under static conditions, all points in a conductor must be at the same electric potential. Give the property of objects which is best measured by their capacitance. Explain. Why sub transient current magnitude is large compared to steady-state current? Why electric current is a sca...
Start wiring in the first switch box. The black wire from the live power cable goes on one of the brass terminals on the first three-way switch. To connect the other terminal to the second switch, use the white wire from the three-conductor cable. Be sure to mark it with black paint...
