Then multiply the resistors under the star. Remember to add the product of resistance of the first row (R5 + R2 + R4) into the second row (2×R1 + R6). Make sure to add the whole thing because this is a two-resistor two-terminal network and the two terms we are adding are actually resistance. The end result is this.
Example 1: R1 = 20 k, R2 = 10 k, R3 = 30 k, R4 = 70 k, R5 = 7 k, R6 = 10 k, R7 = 2 k, R8 = 2 k, R9 = 10 k, R10 = 1 k, R11 = 5 k, R12 = 2 k. Convert the figure 1(a) using Table 1 and Table 2. What is the equivalent resistance in k.s?
All electrical systems eventually experience overcurrents. Unless removed in time, even moderate overcurrents quickly overheat system components, damaging insulation, conductors, and equipment. Large overcurrents may melt conductors and vaporize insulation. Very high currents produce magnetic forces that bend and twist bus bars. These high currents can pull cables from their terminals and crack insulators and spacers. d2c66b5586
