SUMMARY

The discussion focuses on calculating the value of resistance R in a parallel circuit configuration with a voltage of 30V and a current of 10A. The initial calculation incorrectly simplifies R/2 to 1.5 ohms. The correct approach involves applying Ohm's Law and considering the current distribution across parallel branches, leading to a more accurate calculation of R.

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?

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.
