Question

Two resistance r1 and r2 if connect in series then Req = 10ohm.if connect in parallel then Req= 7.5ohm.find the value of r1 and r2.

Answer 1

Explanation:

hii mate hope my solution helps you....

• R¹+R²=10
• $\frac{1}{ {r}^{1} } + \frac{1}{r^{2} } = \frac{1}{7.5}$
• R¹=10-R²....................(1)

1/(10-R²) + 1/R²=1/7.5

R²+(10-R²)/10R² - (R²)²

10=10R² - (R²)²

solve the quadratic you will get value of R.... hope this helps.... mark as brainliest...
