Question

Value of three resistors.

Answer 1

answer is 3,3,3ohms we can solve this by verifying options in parallel connection R(effective)=1/r1+1/r2+1/r3...by substituting options we get effective resistance 1 for option 3

Answer 2

yes ans is 3,3,3 it a only way to find a ans put your option in equation 1/R1+1/R2+1/R3 =1 and R1+R2+R3= 9 and get your ans
