Question

7.
Find the equivalent resistance across points A and B.​

Answer 1

Answer:

3R/4

Explanation:

First two resistance are in series so,

R1eq = 2R which is in parallel with another R2eq = 2R

So, R12eq = R

Now R3eq = R+R+R = 3R which is in parallel with another R so,

1/Req = 1/R + 1/3R

1/Req = 3+1/3R

Req = 3R/4 ans.
