Question

Eight resistance of 4 ohms are connected in the circuit as shown in the figure. The equivalent resistance between A and B is

Answer 1

Answer:

8/3

Explanation:

aob are connected in series while sector ab is connected in parralel to aob so by the formula

r(series)=4+4=8

and 1/r(equivalent)=1/8+1/4=3/8

hence r=8/3
