If an 8/9ohm, 4/3ohm and 2/3ohm resistor is connected in star, find its delta equivalent.(a) 4ohm, 3ohm, 2ohm(b) 1ohm, 3ohm, 2ohm(c) 4ohm, 1ohm, 2ohm(d) 4ohm, 3ohm, 1ohm |

Answer» The correct option is (a) 4ohm, 3ohm, 2ohm To elaborate: Using the formula for the star to delta conversion: R1=8/9+4/3+(8/9)*(4/3)/(2/3) R2=8/9+2/3+(8/9)*(2/3)/(4/3) R3=2/3+4/3+(2/3)*(4/3)/(8/9). |
