Question

Two resistances 1 and 2 are connected in series and then in parallel.
The ratio of the effective resistance of series and parallel combination is *
1 point
O 3:1
O 2:9
O 1.2
O 92​

Answer 1

Answer:

9:2

Explanation:

In series, total resistance = 1+2 = 3

In parallel, total resistance = 1/(1/1 + 1/2) = 2/3

ratio = 3:2/3=9:2
