From the following figure:-
BC and CD are in series connection
Let, the resistance be R1 for series connection BC and CD
___________________________
R1 ➝ (BC + CD)
➝ 10 ohm + 10 ohm
➝ 20 ohm
___________________________
Now, according to given figure:-
R1 and BD are in parallel connection
Let, the resistance be R2 for parallel connection R1 and BD
___________________________
R2 ➝ (1/R1 + 1/BD)
➝ 1/20 + 1/10
➝(1+2)/20
➝3/20 ohm
So, Resultant resistance =>3/20 ohm

Now, Voltage => 6v {given}

OHM's law:-
V=IxR
___________________________
•°• 6 = I x 3/20
➝ I = 6 x 20/3
➝ I = 2 x 20
➝ I = 40A
°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°
Hence, I = 40A
