Question

get 100points and brainliest answer solve this with explaination ​

Answer 1

in the first one we have the resistors connected in series and then connected in parallel

there fore Rs=R1+R2  =100Ω+xΩ

and 25Ω+75Ω=100Ω

now they are connected in parallel

therefore $\frac{1}{R1}$+$\frac{1}{R2}$ = 1/100 + 1/100+x = 1/20

after calculation x= 75Ω

hope that answers your doubt have a nice day feel free to click the brainliest to whoever cleared your doubt better

therefore \frac{1}{R1}

R1

1

+\frac{1}{R2}

R2

1

= 1/100 + 1/100+x = 1/20

after calculation x= 75Ω
