Show how you would connect three resistors, each of resistance 6\ Ω, so that the combination has a resistance of
 
(i) 9\ Ω,
 
(ii) 4\ Ω.
 
R = 6 Ω
 
Case (i):
 
If two resistors are connected in parallel, then their equivalent resistance is
 
iii+ii=iΩ
 
After connecting the third resistor, the equivalent resistance is  Ω.
  
Case (ii):
  
When two resistors are connected in series, then their equivalent resistance is given by
 
R=i+i=iΩ
 
The equivalent resistance is
 
R=ii+ii
 
After connecting the third resistor, the equivalent resistance is  .
