How to do

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
