Find Value of R: Correct Solution?

[noname1]

I have to find the value of R

v1 = 30V

this is how i did it

since R is in parrallel i juts put that R/2

R/2 = 30V/10A = 3ohms/2 = 1.5ohms

is this correct?

 

[Phrak]

R/2 = 30V/10A =

Try it again, multiplying both sides by 2.

Calculating (using valid maths) is probably better, but think about how the current will split through each branch given equal resistance.

Then use Ohms Law.
