Question

Calculate resistance between the A and B in question 3​

Answer 1

Answer:

Explanation:We can assemble the given circuit as given in the attachment now

By wheatstone bridge, the circuit is balanced

So the first combination is in series and the second combination is also in series those two are connected by parallel

1/R=1/5+1+1/5=7/5

1/R=7/5

R=5/7

R=0.71ohm

Answer 2

consider this as a wheatstone bridge so no current through 1 ohm

so , 2ohm +3ohm = 5ohm

again 2ohm +3ohm=5ohm

1/5+1/5=1/R

R =  2.5 ohm
