Explanation:
10 ohm and 15 ohm are in series and also 20 ohm and 5 ohm are in series.
let 10 ohm be R1 , 15 ohm be R2 , 20 ohm be R3 and 5 ohm be R4
therefore,
T1= R1 + R2 = 10 ohm + 15 ohm = 25 ohm
T2 = R3 + R4 = 20 ohm + 5 ohm = 25 ohm
now,
T1 and T2 are in parallel.
1/T1 + 1/T2 = 1/25 + 1/25 =2/25 = 12.5 ohm
therefore,
current (I) = V/R = 45V/12.5 ohm
= 18/5
= 3.6 A
