Answer 1

Answer:

Resistance of ab = 1/1+1/2 =2+1/2 =3/2 ohm or 1.5 ohm

Answer 2

Answer: Final Answer Will Be 0.44..

Explanation:

First of all add Resistance of all in parallel , all are same as we see its 1ohm and 2ohm in each so total resistance of each will be same .

the resistance of top left resistors = total Resistance of top right resistors = total resistance of the bottom resistors . so as they are parallel so the formula -

1/Rp= 1/1+1/2

1/Rp= 2+1/2

1/Rp=3/2

Rp= 2/3

TOTAL Resistance of top left resistors = top right resistors =  

bottom resistors = 2/3

Then the top left resistors and top right ones are in series so 2/3+2/3=4/3

then the top two resistors is in parallel with the bottom one

so -

Total of top two + bottom resistors

1/Rab= 1/4/3+1/2/3

1/Rab=3/4+3/2

1/Rab=3/4+6/4

1/Rab=9/4

Rp=4/9

Total Resistance = 0.444...
