Question

Three equal resistors connected in parallel have
equivalent resistance R/3. When they are connected in
series then the equivalent resistance is:​

Answer 1

Answer:

their equivalent resistance is 1Ω if they are connected in series, find the equivalent resistance

Answer 2

Answer:

The formula for parallel combination is :

= 3 Ω.

If we connect all three Resistances,

in series, 3+3+3 = 9 Ω.
