While estimating domestic wiring cost, if the length of the PVC conduit required is 62 meters, then what is the length of the cable required?

The size of the conduit is 62 meters. In conduit, there is a 2-phase wire and 1 neutral wire. Therefore the total number of conducting wire is 3 in a conduit

Total length of cable = 62 × 3 = 186 meters.

Observe the figure and find the correct relation from the four given options?

According to Kirchhoff’s law states that the current entering a node is always equal to the current leaving a node.

From the above Diagram

Current Flowing towards the Point: I1, I2, I6

Current Flowing Away from the Point: I3, I4, I5

Hence I1 + I2 + I6 = I3 + I4+ I5

Creeping is a term related to instruments?

**Creeping Error**

The slow but continuous rotation of the energy meter (Induction type) when only the pressure coil is excited and no current is flowing through the current coil is called creeping. This error may be due to excessive friction compensation, excessive voltage supply, stray magnetic field, etc.

In order to prevent creeping at no-load, two holes of the same radius are drilled in the disc on the opposite side of the spindle.
