Question

find the total resistance between a and b​

Answer 1

Resistance in series R' = 6+4=10ohm

Let Total resistance br R

Then,1/R = (1/10) + (1/5)

=(5+10)/50

=15/50

=3/10

Therefore,

R = 10/3 = 3.3ohm

Answer 2

Answer:

6 ohm and 4 ohm are series combination

Requivalent =6+4=10 ohm

5 ohm and 10 ohm are in parallel combination

1/R=1/5+1/10=1/10+2/10

Requivelent = 10/3 ohm
