Question

a piece of wire R is cut into 6 equal parts. these parts are then connected in parallel. lif the equivalent resistance of this combination is R '. write the ratio for R /R'​

Answer 1

Good Morning!

R' = (1/R) + (1/R) + (1/R) + (1/R) + (1/R) + (1/R)

R' = (1/R) { 6 }

DIVIDE BOTH SIDES BY R WE HAVE

R'/R = 6/R²

TAKING RECIPROCAL ON BOTH SIDED

R/R' = R²/6
