No of disc required for 11 kV transmission line = 1 disc
Since the transmission line is 3-phase, therefore, the number of discs required for a single-pole will be 3.
Total no. of poles = 80
No of disc = 3 × 80 = 240
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
The wattage rating for a ceiling fan motor is in the range of 50 to 150 W. if the ceiling Fans size ranges from 36 inches to 56 inches then the total wattage use is 55 to 100 watts.. A 48-inch ceiling fan will use 75 watts.
The amount of flux produced by the magnet indicates the strength of the magnet. The more the magnetizing force (MMF), the more is the flux produced. The more the opposition to the flux path (i.e., reluctance or magnetic resistance) less is the flux produced. This relationship is expressed as
Flux = MMF/ Reluctance
Reluctance is the opposition offered by the material in the flux path to the establishment of the flux. The reluctance in a magnetic circuit is similar to the resistance in an electric circuit. Reluctance is the inverse of permeance.
MMF = Flux/Permeance
