11) What is the reason of lamp glowing dim and motor running slow in a domestic wiring circuit?

Open circuit in the neutral line

Short circuit between conductors

High value series resistance fault

Open circuit in the earth conductor

Answer is:

High value series resistance fault

Substations

Godown wiring

Domestic wiring

Commercial wiring

Answer is:

Earthing through impedance

Providing by plate earthing

Increasing conductor size

Providing parallel earthing

Answer is:

Converts A.C. into D.C

Reverses the polarity of D.C

Changes D.C. supply into A.C supply

Reverses the direction of rotation of the generator

Answer is:

Cost is less

More flexible

Less voltage drop

More insulation resistance

Answer is:
