Q45 of 330 Page 43

A resistor of 8 ohm. Calculated in parallel with another resistor X. The resultant resistance of the combination is 4.8 ohms. What is the value of the resistor X?

Parallel combinations of the resistors will be written as

1/x + 1/8 = 1/4.8


On solving the above relation,


x = 12 ohms

You are given three resistances of 1, 2 and 3 ohms. Show by diagrams, how with the help of these resistances you can get :

(i) 6 Ω (ii) C (iii) 1.5 Ω
