Question

find equivalent resistance and current through 7 ohm resistor in following​

Answer 1

First analyse the circuit properly

There are two resistor connected in parallel

so,

1/R` = 1/6 + 1/6

1/R' = 2/6 = 1/3

R` = 3ohm

R3 = 7 ohm

now we will add R` and R3

R = R` + R3

R = 7+3

R= 10ohm
