Question

three resistance of 2ohm each were first conneced in series and then in parallel in circuit find the ratio of total resistance in series and parallel combination.​

Answer 1

Answer:

4 ohm

Explanation:

When Resistance is connected in Series

then

R=R¹+R²

here R is total resistance and R¹ or R² both have value 2 oh

so resultant resists is 4 ohm in series

In Parallel

1/R=1/R¹+1/R²

so R=2×2/2+2=1

so resistance in parallel is 4 ohm

so ratio of resistance in series to parallel is
