Question

for the series combination of three digit establish the relation are equal to R1 + R2 + R3 where the symbol have been that usual meaning calculate the equivalent resistance of the combination of three register 6 2 9 9 18 of joined in parallel​

Answer 1

equivalent resistance of the given combination of resistors is Rp=18/17
solve the equations by the formula of parallel
i.e 1/Rp=1/R1+1/R2+1/R3
