AI Thread Summary
To find the value of R in a parallel circuit with a voltage of 30V and a total current of 10A, the calculation begins with R/2. The initial calculation suggests R/2 equals 1.5 ohms, leading to R being 3 ohms. However, it's advised to reconsider the approach by multiplying both sides by 2 and applying Ohm's Law for accuracy. Additionally, understanding how current splits through parallel branches with equal resistance is crucial for correct calculations.

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.
