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.
The 2’s complement of the number (1010101)2 is found in two steps. First, convert the given number into its l’s complement. 1’s complement of a binary number is just an inversion of individual bits. 1’s complement of (1010101)2 is (0101010)2 To find 2’s complement of the number add one to the least significant bit (LSB). So
In the PMMC type instrument, the deflection is directly proportional to the current flowing through the instrument, we get a uniform scale for the instrument. It gives a uniform scale of upto 270° or more. Td ∝ I
