15) What is the advantage of stranded conductor over solid conductor?

Cost is less

More flexible

Less voltage drop

More insulation resistance

Answer is:

More flexible

Providing double earthing

Reducing the pit depth for earthing

Increasing the length of the electrodes

Decreasing the length of the electrodes

Answer is:

Provide electrostatic shield

Protect the coils in the meter

Reduce the value of current in the meter

Avoid the effect of electrolytic emf interference

Answer is:

It is not having controlling Torque

Provided with air friction damping

The deflecting torque is directly proportional to the current

The deflecting torque is directly proportional to the square of the current

Answer is:

Current in current coil

Current in potential coil

Speed of the handle rotation

Ratio of the current in two coils

Answer is:
