The sequence of coloured bands in two carbon resistors R_1 and R_2 is (i) brown, green, blue and (ii) orange, black, green. Find the ratio of their resistances. |

Answer» Solution :As per colour code FOLLOWED resistance of (i) RESISTOR `R_1` having brown, green and blue bands is `R_1 = 15 XX 10^6 Omega` (ii) Resistor `R_2` having orange, BLACK and green bands is `R2 = 30 xx 10^5 Omega` `R_1/R_2 = (15 xx 10^6)/(30 xx 10^5) = 5/1` |
