Answer:
30 ohms
Explanation:
in 1st loop let current say i1
in 2nd loop let current say i2
taking KCL in 1st loop
-100 + 10i1 + 10i2 = 0
-100 + 10i1 + 10 ( 2) = 0
-100 + 10i1 + 20 = 0
10i1 = 100 - 20
10i1 = 80
i1 = 8 Amperes
Taking KCL in 2nd loop
10i2 - 10i1 + Ri2 = 0
10 (2) - 10 (8) + R (2) = 0
20 - 80 + 2R = 0
2R - 60 = 0
2R = 60
R = 30 ohms
