Question

how will you connect 3 resistance of 2ohm, 3ohm and 6ohm to obtain total resistance by a) 4ohm b) 1ohm​

Answer 1

Answer:

Explanation:

(A) 4 ohm

3&6 ohm resistors are in parallel so 1/R(3//6) = 1/3+1/6 ;R(3//6)= 2 ohm and these are in series with 2 ohm resistor therefore Rnet = R(3//6) + R ; R = 2+2 = 4 ohm (b) 1 ohm all the resistors are in parallel so 1/Rnet = 1/3 + 1/6 + 1/2 ; 1/Rnet = (2+3+1)/6 ;1/Rnet=6/6 ; Rnet= 1 ohm
