Dear Student,

​​​​​​Figure 1: 
V = 10V
I = ?
 
We now have to find out R.
Resistance can be calculated in this case by connecting the two resistance in parallel
So, 1/Req = 1/5 + 1/5 = 2/5 
So, Req = 2.5 ohm

This Req is then connected in series with the 5ohm resistance in series connection.
So, R = 2.5+5 = 7.5 ohm

Using V = IR
10 = I x 7.5
I = 4/3 ohm

P.S. Kindly post separate questions in separate threads.

Regards
